FP monopolises CPU

Why does FlashPlayer take over the whole CPU capacity (98%) and slow my PC to a crawl?

Hi Mike,
I'm sorry to hear that you've run into so many problems in the past.
Hopefully we can try to figure out what is going on here. You mentioned
in the first post that there appears to be a communication problem with the
cFP-2020 that you have. In the first post you mentioned that power
cycling the module appears to fix it, so I doubt its actually a problem with
the connections or how they are made. That means we should probably focus
on the software and how it is interacting with the hardware.
You mentioned that you would like some way of confirming that the data is
coming from a working module (a "quality" bit
I can read). One way that you could do this is read the
Ready LED on the Controller and if that toggles state then it means that something
erroneous is occurring.
You might also want to look in the cFP-20xx
User Manual , particularly in Appendix A where it mentions what the
flashing LED light indicates. As you can see, different numbers of
flashes correspond to different issues.
You mentioned that you contacted Tech Support on Friday and
that they seem to have misdiagnosed the issue. I would highly recommend continuing
working with them and explaining to them why it is not a network issue (which
shouldn't take long seeing as you are able to communicate with the
module). National Instruments' Applications Engineers pride themselves on
being able to help our customers, and if they gave you information that did not
help the first time, then they can use the knowledge they already have of your
system to help you find the best solution possible.
Ultimately, since we are dealing with computers there is a
logical reason as to why you are getting this error. While it may be
difficult to diagnose because of the long mean-time between failures, there is
a solution or a workaround out there that can get your system back up and
running.

Multi-user multi-head setup

Purely out of curiosity, I would like to create the following setup:
Computers: 1 (i.e. 1 motherboard)
Physical displays: N
Keyboards, mice: N
Processor: >= N cores
...and have a separate tty allocated to each monitor/mouse/keyboard group such that N non-root users can simultaneously work on a single box, in independent desktop environments and unable to interfere with each other. The processor criterion is to ensure that each user has at least one core "of their own" via affinity masking, so no one user can monopolise CPU resources. RAM and I/O resources are something that I'll think about at a later date.
The idea is to allow multiple non-root users to simultaneously work on one computer in such a way that they cannot interfere with each other's sessions in any destructive way (e.g. reboot, kill processes, hijack session, etc).
Could anyone point me in the right direction ( configurations / supported graphics vendors / kernel parameters ) for this?
I have no real use for this (particularly with how cheap VDI is), it is purely an academic curiosity.

@Nattgew:
Cheap USB video adapters will be fine for testing, and I can probably bag some powerful old Radeons (48xx) on the cheap, each of which will drive at least 2 screens. Alternatively, I could probably daisychain a bunch of higher-end cheap monitors (e.g. Dell U2312) via DisplayPort.
@slithery:
Cheers! I got nothing but flaming when I asked on the Ubuntu forums, you've solved the problem in a single word ("multiseat")!

Computer loses time during datalogging

When datalogging using a Dell Inspiron laptop, Labview 6.0.2, Windows 2000, NI DAQcard 1200 the computer clock runs slow (at least the clock used for file timestamping when file write vi's are called, and the windows clock are affected. I'm not sure about the time value returned by the time reading vi's). The datalogging is at high sampling rates, but in bursts of two per second, with sufficient pauses in the vi so it doesn't monopolise cpu time or anything. The clock loses perhaps 1 minute every 10 minutes, although it will jump back to the correct time periodically after an hour or so.
I have also noticed this several years ago using an earlier Dell portable with windows 95, although the time never recovered in this case - it j
ust got further and further behind.
Can anyone explain why this happens?
If it is an effect that cannot be changed, is there a simple way to refresh the windows clock from within labview.
thanks

I also read that thread but there are different issues in my case. Their solutions are to run third party software to synchronise the clock with another computer. I am using a portable computer and don't even have connection to mains power let alone LAN or internet access to other computers clocks so this is not an option. Besides, my computer DOES know what the correct time is. It periodically realligns itself, or a reboot would reset the time correctly as well, so there must be someway to read the real time. Can labview be used to read the bios clock and not the windows version?
My code has plenty of waits in it, and at least 50% of cpu time is free averaged over any 1 second period. This is not the problem.
I'm not familiar with what is meant
by DAQ occurrences but will look into it to see if it helps.
Thanks,
Steve

How to set up notification email for Full CPU utilization on OEM12c?

I have found a Oracle Doc,Is that's the way email notifications are setup?How can i check that after setting the notifications?
4.1.2.3 Subscribe to Receive E-mail for Incident Rules
An incident rule is a user-defined rule that specifies the criteria by which notifications should be sent for specific events that make up the incident. An incident rule set, as the name implies, consists of one or more rules associated with the same incident.
When creating an incident rule, you specify criteria such as the targets you are interested in, the types of events to which you want the rule to apply. Specifically, for a given rule, you can specify the criteria you are interested in and the notification methods (such as e-mail) that should be used for sending these notifications. For example, you can set up a rule that when any database goes down or any database backup job fails, e-mail should be sent and the "log trouble ticket" notification method should be called. Or you can define another rule such that when the CPU or Memory Utilization of any host reach critical severities, SNMP traps should be sent to another management console. Notification flexibility is further enhanced by the fact that with a single rule, you can perform multiple actions based on specific conditions. Example: When monitoring a condition such as machine memory utilization, for an incident severity of 'warning' (memory utilization at 80%), send the administrator an e-mail, if the severity is 'critical' (memory utilization at 99%), page the administrator immediately.
You can subscribe to a rule you have already created.
From the Setup menu, select Incidents, then select Incident Rules.
On the Incident Rules - All Enterprise Rules page, click on the rule set containing incident escalation rule in question and click Edit... Rules are created in the context of a rule set.
Note: In the case where there is no existing rule set, create a rule set by clicking Create Rule Set... You then create the rule as part of creating the rule set.
In the Rules section of the Edit Rule Set page, highlight the escalation rule and click Edit....
Navigate to the Add Actions page.
Select the action that escalates the incident and click Edit...
http://docs.oracle.com/cd/E24628_01/doc.121/e24473/notification.htm#CACHDCAD

Make sure you have correct thresholds...

T410s with extremely poor performance and CPU always near 100% usage

Hi,
I've had my T410s for almost a year now and lately its been starting to get extremely slow, which is odd since it used to be so fast.
Just by opening one program, Outlook, or IE or Chrome, just one window, it will start to get extremely slow and on task manger I can clearly see the CPU usage at 100% or very near.
Also another thing I noticed was the performance index on the processor dropped from 6.8 to 3.6!!!
I did a clean Windows 7 Pro 64Bit install, I have all Windows and Lenovo updates installed and the problem persits
What is happening and what should I do??
Thank you
Nuno

thank you again for your answer,
I've done that but hard drive health is also ok as you can see from the screenshot.
IAt the time of the screenshot I had just fineshed to boot up the laptop and it wasnt hot at all.
I am getting desperate here, I am unable to work with my T410s

Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

Firefox consumes a lot of CPU resources

High CPU usage while running a java program

Hi All,
Need some input regarding one issue I am facing.
I have written a simple JAVA program that lists down all the files and directories under one root directory and then copies/replicates them to another location. I am using java.nio package for copying the files. When I am running the program, everything is working fine. But the process is eating up all the memories and the CPU usage is reaching upto 95-100%. So the whole system is getting slowed down.
Is there any way I can control the CPU usage? I want this program to run silently without affecting the system or its performance.

Hi,
Below is the code snippets I am using,
For listing down files/directories:
        static void Process(File aFile, File aFile2) {
          spc_count++;
          String spcs = "";
          for (int i = 0; i < spc_count; i++)
          spcs += "-";
          if(aFile.isFile()) {
               System.out.println(spcs + "[FILE] " + aFile2.toURI().relativize(aFile.toURI()).getPath());
               String newFile = dest + aFile2.toURI().relativize(aFile.toURI()).getPath();
               File nf = new File(newFile);
               try {
                    FileCopy.copyFile(aFile ,nf);
               } catch (IOException ex) {
                    Logger.getLogger(ContentList.class.getName()).log(Level.SEVERE, null, ex);
          } else if (aFile.isDirectory()) {
               //System.out.println(spcs + "[DIR] " + aFile2.toURI().relativize(aFile.toURI()).getPath());
               String newDir = dest + aFile2.toURI().relativize(aFile.toURI()).getPath();
               File nd = new File(newDir);
               nd.mkdir();
               File[] listOfFiles = aFile.listFiles();
               if(listOfFiles!=null) {
                    for (int i = 0; i < listOfFiles.length; i++)
                         Process(listOfFiles, aFile2);
               } else {
                    System.out.println(spcs + " [ACCESS DENIED]");
          spc_count--;
for copying files/directories:public static void copyFile(File in, File out)
throws IOException {
FileChannel inChannel = new
FileInputStream(in).getChannel();
FileChannel outChannel = new
FileOutputStream(out).getChannel();
try {
inChannel.transferTo(0, inChannel.size(),
outChannel);
catch (IOException e) {
throw e;
finally {
if (inChannel != null) inChannel.close();
if (outChannel != null) outChannel.close();
Please let me know if any better approach is there. But as I already said, currently it's eating up the whole memory.
Thanks in advance.

Attn: ALL APPLE PORTABLE OWNERS -Macbook Pro, MacBook Air Apple portable slowdown / kernel high CPU solution

Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
YOUR MAC WILL THANK YOU
Hey all.
Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue
I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
User Software Symptoms :
Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
Possible Hardware Symptoms:
Your computer is making more noise than it did previously.
Your computer occasionally makes more noise but then gets quieter.
Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
After trying many different things to solve this problem such as :
PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
After much testing I found the problem :
It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
One app shows fan speed, and CPU heat, etc.
One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
One app is a dashboard widget, the other is a system preference.
I suggest you download both of these to check your computer statistics.
http://www.eidac.de/?p=134
http://www.islayer.com/apps/istatpro/
http://fan-control.en.softonic.com/mac
I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
If a bad fan is your problem :
THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
Fix or replace your fan so it cools the CPU and other chips properly.
I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new. It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
How to fix / replace your internal fan on a mid 2009 MacBook Pro :
Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
Before you begin:
Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):
http://www.youtube.com/watch?v=AghE9newvbs
Check out someone's web page (not mine) on how to replace the fan in a mid 2009 MacBook Pro:
http://www.ifixit.com/Guide/Installing-MacBook-Pro-13-Inch-Unibody-Mid-2009-Fan/ 1338/1
How to repair your mid 2009 MacBook Pro fan:
Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc.
Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
3. Unscrew the fan's 3 holding screws.
4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
5. Remove the fan - it easily lifts out.
6. Take the fan apart by unscrewing it's one screw then unlatching the plastic clips which hold it together.
7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
Screw together the fan housing then reclip the clips.
11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
14. Double check you didn't forget anything like screws, tools, etc.
15. Boot up your Mac and monitor the temperature and fan speed using those programs.
Compare the previous temps/fan speed to the current temp/fan speed.
Run a high CPU intensive app where your computer has been slowing down.
You should now have a happy Mac
If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
Hope that helps.

Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

Win 7 pro 100% cpu with only a few programs running

I have a 4.2 rating with a amd athlon 64 3400+ running at 2.41ghz, 2.5 gig ram in 32bit windows 7 pro. My motherboard doesn't have windows 7 drivers which may contribute to the issue. Asus k8N so I have no illusions that this computer should be lightning quick but it is very difficult to keep my patience due to the high cpu constantly. I run about the same as I did in XP and I didn't have nearly the high cpu usage. Outside of antivirus (AVG free), logmein, creative camtray, and tversity running all the time. If I then open Outlook 2007, Firefox more then one tab and itunes, my cpu is at 100%, it's still usable for a definite slow down. I've set the visual effects to best performance and that really hasn't made a difference. What suggestions can you offer other then stopping logmein, the camtray, and tversity all of which are not using hardly any cpu. It's constantly flipping between firefox and itunes primarily.

Hi Cougar78,
I would like to confirm what process uses the high CPU usage you find with Task Manager?
You may update the BIOS and the hardware drivers first to check the issue.
If it does not work, I also would like to suggest you test the issue in Safe Mode and Clean Boot.
What are the results in both modes?

Alto consumo de CPU

Esta não é exatamente uma pergunta, mas um relato para talvez servir de pista para o problema em si.
Fiz o upgrade do windows 7 para o windows 8 com a opção de manter os programas e dados.
Após o upgrade o Firefox passou a apresentar um alto consumo de CPU, apenas abrindo o mesmo, sem navegar e tendo a pagina de busca do google como padrão.
Mesmo abrindo o Firefox com todas os puglins desabilitados o alto consumo permanece ao executar o firefox, sem nenhuma navegação.
Desde o FF 17, baixo as atualizações mas continua acontecendo o problema (até pelo menos o FF 19)
Fazendo o "Reset Firefox to its default state" da pagina about:support, funcionou uma vez, mas logo voltou a acontecer o problema
Recentemente vi o artigo https://support.mozilla.org/pt-BR/kb/Firefox%20est%C3%A1%20rodando%20mas%20n%C3%A3o%20est%C3%A1%20respondendo
Então resolvi excluir o diretório do profile e magicamente o FF voltou ao normal.
Tudo muito bom, mas ai tive que reiniciar o computador por um motivo qualquer e ao abrir o FF, ele novamente apresentou o problema de consumo de CPU.
Então percebi que se apagar o profile, ele cria um novo e funciona normalmente , posso abrir e fechar o FF quantas vezes quiser e o problema do consumo não ocorre.
Basta reiniciar o computador e o problema volta.
Então creio que existe algum problema que ocorre com o profile.
Fiz o procedimento varias vezes, não instalei nenhum plugin extra e somente abrindo e fechando o FF na sua pagina default e sempre que se reinicia o computador, o problema volta.
Por ora, infelizmente resolvi meu problema trocando de navegador e como o Thunderbird estava apresentando o mesmo problema de alto consumo de CPU tive que abandonar os softwares da Mozilla
mesmo gostando muito deles.

== Answer ==
lkmatsumura, <br />Sorry you are having problems.
So in summary you seem to have problems with both Firefox & Thunderbird but that is temporarily solved with a new profile, but returns once the computer is restarted.
I do not know what is causing that but my first thought is do you have any security or recovery software that is resetting firefox, or modifying the profile.
If you do consider using Firefox again as a first step back up your profile
*[[Back up and restore information in Firefox profiles]]
The next steps will be troubleshooting the problem, and probably doing a clean install. If necessary I can provide further instructions.
Incidentally Firefox has a known crashing problem currently if Firefox 19 is used on some AMD PCs using Windows 8.
== Q ? (I used [http://translate.google.com/#auto/ Google translate] )==
This is not exactly a question, but maybe a story to serve as a clue to the problem itself.
I upgrade windows 7 to windows 8 with the option to keep the programs and data. After upgrading Firefox now provides a high CPU consumption, just by opening it, without having to browse and search page of google as default. Even opening Firefox with all the puglins high consumption remains disabled when running firefox with no navigation.
Since FF 17, down updates but the problem keeps happening (at least until the FF 19)
Making the "Reset Firefox to its default state" of the page about: support, it worked once, but then it happened again the problem
I recently saw the article
So I decided to delete the profile directory and magically the FF returned to normal. All very good, but then had to restart the computer for some reason and when you open the FF, he again presented the problem of CPU consumption. Then I realized that if I delete the profile, it creates a new and works normally, I can open and close the FF number of times and consumption problem does not occur. Just restart the computer and the problem returns. So I think there is some problem in the profile. I did the procedure several times, did not install any extra plug-and only by opening and closing the FF in your default page and whenever you restart the computer, the problem returns.
For now, unfortunately solved my problem by changing the browser and the Thunderbird was presenting as the same problem of high CPU consumption had to abandon the Mozilla software even really enjoying them.

Falta ao Magic Mouse compatibilidade de hardware para o terceiro click! Aplicativo consome muito processamento da CPU. Haveria como a Apple tornar este um gesto padrão?

Caros,
Existem diversos programas que utilizam o terceiro click como atalho de comandos, principalmente os de criação e edição em 3D.
Estes atalhos realmente aumentam a produtividade do trabalho no software: zoom, orbit, pan, etc...
Entretanto, após adquirir um Apple Magic Mouse tenho de me abster de usar estes atalhos, causando uma grande lentidão na produção.
Tentei instalar aplicativos que fazem a interpretação de outros gestos no mouse a fim de suportar tais interações.
Entretanto, há o consumo de quase 10% da carga da CPU nesta tarefa! Não há condições de trabalho com os diversos "soluços"do sistema, além de que estes aplicativos falham na interpretação constantemente, tornando a solução inaceitável.
Acredito que com uma adoção via hardware do terceiro click, com um gesto nativo do próprio mouse, traria grandes benefícios para todos que utilizam este Magic.
Alguém sente falta, ou sou apenas o único?!

Firefox 29 con un terrible uso de CPU al reproducir un video (plugin-container)

Para probar lo mal que este navegador se despempeña al reproducir un video: usar una computadora con Intel Celeron D, 2 Gigabytes de RAM y una nivida GeForce 7200 GS/7300 SE, si no se cuenta con una computadora similar... entonces probar la ineficiencia TOTAL de este navegador seria imposible.
En fin, ya que se tenga un precesaor de un solo nucleo y pocos gigabytes de RAM, se comienza la prueba.
para probar hay que entrar a este sitio desde firefox: http://cnnespanol.cnn.com/2014/05/12/nasa-la-contraccion-de-glaciares-en-la-antartida-es-irreversible/
bueno, en fin el problema que tengo es que Firefox usa DEMASIADO CPU, para reproducir un solo video de flash... mientras resproduzco un video ese proceso desagradable y maldito llamado "plugin container" usa el 100 % de la CPU y he tenido temperaturas barbaras tanto en Windows 7 32 bit como Ubuntu 64 bits que llegan a los 71 grados celsius, todo por ese MALDITO e INEFICIENTE proceso que se llama plugin-container y como no! el INEFICIENTE api que ellos llaman NPAPI...
Si ustedes, Mozilla reciben dinero... en lugar de usarlo en cosas inutiles como Australis, deberian usarlo para mejorar la eficiencia de ese maldito plugin-container.
¿En que momento decidieron que su navegador tenga que funcionar solo en computadores con 12 nucleos?
En fin he tratado inutilmente lo que aqui se sugiere, desactivar la aceleracion por hardware tando de firefox como de flash... e incluso empeora, teniendo desactivado la aceleracion por hardware, hay videos que simplemente no puedo ver, el video es entrecortado y los controles del reproductor embebido son irresponsivos.
En fin... mi computadora puede parecer muy pobre para ustedes señores de Mozilla, pero a me srive todavia y creo que puede durar mucho mas, al menos hay otros programas con lo cuales no tengo este problema y me son utiles... y la verdad no necesito gastar dinero para comprar una computadora con la caracteristica que he descrito anteriormente, pero ¿en verdad necesito tirar mi dinero a la basura para poder ver videos decentemente?

Hola,
Gracias por su pregunta. A este momento si la plugin napi estaba usando mas de 100% de la CPU, por favor desactivar la plugin.
Por favor actualice sus controladores y WebGL también. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Muchos gracias.

Adobe, please stop running from this issue! (GPU vs CPU anomalies / fades)

Adobe,
I have tried to bring this issue to light many times, and your own users have argued it ad finem, but to no avail! I am TIRED of getting terrible alpha blending (and opacity curve) results with GPU acceleration enabled, vs CPU. In fact, it is SO BAD that I NEVER work with GPU acceleration any more.
Here is the issue:
When GPU acceleration is enabled, you simply CANNOT do a smooth fade and/or cross dissolve. It appears to fade down smoothly to about 20% opacity, and then the next frame it will jump right to 0% quite abruptly and disappear. It's almost as if the fade simply gives up and switches off! Regardless of whether you use Cross Dissolve, or Film Dissolve the results are the same. Also, your alpha blending is all messed up, CLEARLY showing a different result when comparing CPU and GPU rendering outputs. Once again, this issue ONLY exists with GPU acceleration ENABLED. Switch off GPU/MPE and the problems disappear. But of course you lose the speed and other benefits GPU acceleration offers, which would be great to have! Especially seeing as I have also heard (from various other resources) that GPU acceleration can improve the quality of rendering out to compressed formats like H264. But we will never know that, will we? Because, every time I enable GPU, my fades and blending looks noticeably bad!
I have seen in various other threads that your response has been along the lines of: "That's just the way it is". But unless your name is Bruce Hornsby, this response is unacceptable! You cannot advertise a "great feature" of your products (in this case, GPU/MPE), yet when people try to use it and see odd results, simply tell us: "oh by the way, yeah, it does not work in a few scenarios, like fading, but otherwise you are good to go!" The way I see it: cross-fades (even fades in general) as well as opacity/blending are some of the most common, if not THE most common techniques used in video projects! Having an anomaly of this nature showing a DISTINCT difference in quality output when one of your fantastic "features" is enabled is just poor form. What is evern poorer is your responses (or lack thereof) related to the issue. Especially seeing as this problem has been present since CS5, and now we are STILL seeing it in CC!
Here is a thread which documents the issue well (even shows examples, and other details someone prepared for you to apparently ignore):
http://forums.adobe.com/thread/773441
...it was never addressed there.
Another issue which details it going back as far as CS 5.5:
http://forums.adobe.com/thread/987306
...once again, never resolved.
Now I am using CC, latest version, up-to-date, a fast i7 processor, a CUDA supported card, and all of those go to waste because I have to have GPU and the mercury playback engine disabled to yield decent quality results.
I implore you, not just for myself, but on behalf of everybody here who has already addressed this issue, but has had their pleas fall on deaf ears: PLEASE FIX THIS PROBLEM. Telling us simply that: "This is the way GPU cards choose to render" is NOT ACCEPTABLE. It's just like me saying when I drive my car on the wrong side of the road: "that's just the way I drive!". Doesn't mean it is acceptable!
You may have won people over since Final Cut Pro screwed the pooch with version X... but I can guarantee if this does not get resolved soon, the issue won't just be isolated to the forums here. Expect to read about it in MANY online publications that I am sure your competitors will ENJOY watching!
Mat.

Indeed. Yes Adobe, please explain.
And here is an example of what I am talking about:
CPU only (MPE and GPU DISABLED):
This appears to be what I would consider accurate, as it is not only well blended, but the fades work smoothly thanks to it relying on the CPU...
GPU (MPE and GPU ENABLED - Linear Color ON - as per default):
This provides identical image quality/blending results as the CPU only benchmark. However, the fades are very abrupt, as per the original problem...
GPU (MPE and GPU ENABLED - Linear Color OFF, as per your recommendation):
This is your recommended solution. The fades are as smooth as they are in the CPU version. But as you can see the color, alpha and blending are VASTLY different. Actually, it looks HORRIBLE! The BG text is barely visible, and the foreground text appears to be more prevalent over the top of the back layer, making its fade-up quite disjointed and selective.
...So as you can see, the "solution" you provided seems to create more problems and/or inconsistencies in the overall output. Now we have no idea what is the "standard"!
I personally find these inconsistency's very concerning. And I am sure I'm not the only one. Please tell me there is actually a logic to this "solution" and it wasn't a simple duct-tape fix that nobody there at Adobe actually looked deeper into to see exactly how it would effect overall image quality! It sure appears that way!
I appreciate that you, Kevin, are not directly responsible for this issue, and you are indeed a representative trying to help. But please realize that for many of us here, we are LONG time Premiere users, with years of experience and influence in this industry, and this definitely isn't our first rodeo! When we flag these issues we do so out of a REAL need, which means the consequences Adobe faces as a result of not addressing these issues are equally as REAL! As such; I encourage you to expedite the process of resolving this issue, because it has been prevalent since CS5.5, and the fact that it is not been resolved and/or has been addressed poorly does not bode well for your overall reputation. Especially when you are trying to make Premiere the industry standard. Like I said, I would hate to have to look at alternatives, so give me a solution, because if I decide to move on from using Premiere, I won't be the last. And no, I am not being melodramatic here. If a piece of software cannot seem to get something as simple as fades and blend modes right (or at least CONSISTENT), how can the software be trusted to handle high-end workflows? Food for thought.

Load on 2 CPUs is smaller than 2 times load on 1 CPU, how to improve?

Good afternoon,
I am trying to improve the performance on my system.
I have used "pbind" to fix a process on a CPU, like this:
Process P1 -> CPU 1
Process P2 -> CPU 2
Every process uses Oracle access (although most of the data are loaded into memory) and a connection towards another central process.
The problem now is the following:
if I launch process P1 50 times/second, the first CPU runs on 22% idle.
If I launch, next to P1, process P2 also 50 times/second, both CPUs (1 and 2) run on 19-20% idle.
If I launch, next to P1 and P2, process P3 also 50 times/second, all three CPUs (1, 2 and 3) run on 16-17% idle.
As my systems contains 16 CPUs, at the end, I loose 56% performance.
Now I wonder what is the nature of this performance killer? Is it simultaneous disk access, simulateneous interprocess communication, is it a purely UNIX related issue, is it an Oracle problem, ...?
Can anybody give me some ideas which could be the problems and how to investigate how to detect and verify them?
Thanks
Dominique

Try this, almost identical, but with less execution time.

Huge CPU using : where does it come from ?

Hi,
I programm this beginning of game. It's prettty simple , a charachter which rotates following the mouse pointer. The problem is that this simple application uses about 66% of my Athlon 2200+ when I move the mouse.I don't understand , ok there are some mathematics operations and i use two images to do a clip effect , but that's impossible to do a game without that , that's nothing compared with a real game ...
So can you try to look at my code and tell my why it uses the CPU so much ... and if u have any suggestions about my programming you're welcome
Thx.
Julien.

I changed your main a little
public Engine()
          super("J-WAR");
        getContentPane().setLayout(null);
        setSize(800,600);
        this.getContentPane().setBackground(new Color(0,0,0));
        Engine2d_ = new Engine2d(10,10,600,550);
        getContentPane().add(Engine2d_);
    public static void main(String args[])
     Engine jw = new Engine();
        jw.setDefaultCloseOperation(EXIT_ON_CLOSE);
        jw.setVisible(true);
        jw.pack();
    }your right about the cpu stuff
I did a test on other code samples that use java3d, and guess what, same thing.
What you are worried about, I think is not a problem.
I think you could put thread priorities on it, but that might slow it down.
You could also , rather than have it 100% active on the mouse, make it only move with mouse click??
