CPU usage and memory

What is FF doing when it sets at idle with nothing streaming , playing or such and uses 40-70% of CPU and memory usage keeps on going up. I just set there and watch in the task manager. Every other program uses nothing,
There has to be a programmer intelligent enough to fix this. this has been going on for years.

SImple fact is there is all "fixes" and answers are bogus. Just try using the same tabs in any other browser.
Right now Opera is 2-3% idle no memory problems. other browsers are similiar and I will post.
Mozzila is just like Microsoft . They have no desire to fix the problem

    ...further research and learning. 
    Here is a good tutorial on Java.  Evidently, what I called "jobs" is referred to as processes and threads in this tutorial.  The tutorial states that multithreaded execution is an essential feature of the Java platform which explains the avalanche of threads I observe.  However, I am still stumped at what causes the avalanche of threads and excessive CPU consumption for such a mediocre task.  Also the system log says that IcedTea has an error stating "Application title was not found in manifest. Check with application vendor".   I interpret this to mean that IcedTea does not recognized some application.  What application?  .....the applet?

  • How to monitor CPU usage and performance on a Hyper-V server with several VM's

    I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system.
    I have set up three Virtual Machines, all running Windows 2008 32 bit.
    Build server, running Team City
    Staging server
    SQL Server, running SQL Server 2005
    I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.)
    So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

    First, you have to remember that in Hyper-V that the "host" is called a parent partition and it really just like a virtualized guest with special permissions and roles. Just like any other child/guest, when you open up Task Manager, you can not see the CPU
    usage of the other children on the server.
    Ben Armstrong has a good explanation of this here:http://blogs.msdn.com/virtual_pc_guy/archive/2008/02/28/hyper-v-virtual-machine-cpu-usage-and-task-manager.aspx
    To summarize his post, you need to check three things to get an accurate picture of CPU utilization:
    View the CPU usage on each guest - this is available through Hyper-V Manager or Performance Monitor.
    CPU usage due to context switching - this is the perfmon counter called % Hypervisor Run Timeunder Hyper-V Hypervisor Virtual Processor
    Child partition worker process - vmwp.exe running on the parent partition (1 per child). This handles Hyper-V operations like saving
    state.

  • High CPU Usage and Temperature

    I've recently purchased a MacBook with the latest updates, including the firmware for the random shutdowns but lately when I boot the MacBook up, the fans kick on and it reads 83 degrees Celsius with about 65% CPU Usage and I don't have anything running except what came on the MacBook in itself, any suggestions?? Apple told me to take it in to have it looked at but I was wondering if there is anything I can fix perhaps?? Thank you

    Sometimes when I connect an external drive which I have made drastic file changes to, there are two process that eat up a lot of cpu power and get the macbook really hot for awhile, those two processed are related to the way spotlight tries to re-index the external drive or the internal hd itself if I had made drastic changes to it too.
    Could it be that?
    You can see them show up in Activity Monitor, they are mdimport and another one starting with md(something) too.
    Hope that helps (if that's the issue)

  • Microsoft Office 2004 -- extremely high cpu usage and virtual ram

    hi,
    when i use office it causes a very high cpu usage even when its in idle mode.
    i am unable to work with it, because its extremely slow.
    does anyone have same experiences?
    thanks for your help!
    mbp 2.0 1,5gb ram 80gb hdd   Mac OS X (10.4.7)  

    I am able to work OK with office, I'm using the 'old version' Microsoft Office v.X, not much details in the About Box, just listed as MSoft Word/Excel/etc for Mac service release 1.
    I get the occasional crash, and I have seen Word in particular use 90% of a single core and amazingly large virtual memory usage, gigabytes sometimes, but eventually the document gets printed.
    It shows how useful the dual core (or quad) cpu approach is!
    One cpu for Word to print, and one cpu to run the rest of my applications/life!
    I still use this old office rather than re-booting into Window§ for whatever is the latest version of office.
    Doing some playing with a similar one page document in Office v.X and Pages 2.01, I get Word using about 25% of a core , Pages using 5%, - whilst editing; Intel native Pages has 20% of a core and 80MB ram 480 virtual whilst printing, Word has about 100% of a core and 65MB ram 650 virtual whilst printing, but it is a powerPC code so Rosetta is in there somewhere.
    check Activity Monitor or other apps/widgets for some parasitic processes? have fun!

  • Recently FireFox often has been causing 100% CPU usage and locks up until it finishes the process (various ones). Clearing cookies/cache didn't help. Any ideas?

    Windows 2000 SP4, 1g RAM, Firefox 9.0.1
    We keep IE6 and Firefox open simultaneously for 2 different mail accounts. Firefox was always much faster even with 3 or 4 tabs open, but for the past couple of weeks when trying to update a screen the CPU suddenly goes to 100% usage and of course nothing will move until the particular process is finished. Closing one or more tabs does not help. If I close Firefox completely with Task Manager CPU usage goes back down to nil. After restarting Firefox CPU usage may or may not go back up depending upon whether it tries to continue the previous task that was locking it up.
    It did not do this with Firefox 3.6 but then again it didn't happen immediately after updating to 9.0.1 either.

    100% CPU usage occurred most often toward the end of the working day when busy trying to print on-line postage. We don't have any memory-consuming plugins but according to the knowledge base articles Firefox memory usage can gradually increase during the day even if you do nothing. It seems that may be the problem so we close and restart Firefox more often now as that usually fixes the problem. However, if we get stuck on a particular website update that causes the CPU to to go 100%, we can always start Firefox without previous tabs so the update will stop, or simply use a different browser until we have time to let the computer play games with itself.
    So our workaround of restarting Firefox turns out to be the final solution (until we find something better - will post it if we do). Vic

  • Why Firefox Has Spikes In CPU Usage And Consumes A Lot Of RAM Since Security Update?

    After applying security update 3.6.18 i started having this problem. I had this problem earlier but it only happened after several days Firefox was opened constantly. Now i have this problem several hours later after launching Firefox.
    [http://i.stack.imgur.com/PJmH5.png '''Here is a picture of high RAM usage''']
    '''[http://i.stack.imgur.com/tjsqt.png Here is a picture of high RAM and CPU usage]'''
    I have Flash disabled.
    What is going on? Should i reinstall Firefox 3.6.18?

    Have you any particular reason for using an older version of Firefox.
    Whilst I rarely use firefox 3.6 now, and do not know the answer I will comment that the now unsupported firefox 4 did have bad memory problems in some cases. Some of those problems were addressed in firefox 5, and others are addressed in Firefox 7, which is due out on the Aurora channel next week.
    You could consider upgrading to a newer version of firefox. If you need firefox3.6 only for limited use you could consider using Firefox portable, alongside a newer version of Firefox.

  • Need to limit ram per user +cpu usage % and internet speed

    I go into Windows System Resource Management but I only see limit by process. I need to be able to say limit "greg" to only be able to use a total of 5GB of ram and say 10% of the total available cpu usage. I saw some people suggesting to set up
    proxies for speed limiting but have no idea on how to go about doing that. Or if any1 has any software ideas like I'v tried Net Limiter 3 b4 but it was buggy and stopped other things from working properly on my pc plus don't know if I can use it on server.
    so just to clarify if they are running 1 program they can only uses say the 5GB of ram or if there using 5 differant programs there still limited to only using 5GB of ram.
    Thanks all in advance,
                                        Blue

    Hi,
    You can use the System Resource Manager if you are using the Server 2008R2 or previous edition server, You can set an upper limit on the working set of a matched process,
    but about the RAM limits there have some additional considerations:
    • Do not use memory limits in Windows System Resource Manager to manage applications or processes that modify their own memory limits dynamically. This can interfere with
    the correct operation of Windows System Resource Manager and the managed application.
    •As a best practice, use CPU targets to manage resources. Apply memory limits selectively to applications that exhibit memory consumption issues. Excessively limiting the
    memory that is available to an application can increase the time it takes the application to complete a task, and it can increase disk usage.

    Rundll32.exe Using High CPU on Windows 8.1
    I use a Lenovo T440s laptop for my service calls and when I need to do work remotely. My laptop runs Windows 8.1 Professional. I love this laptop and it has proved to be tough as well as extremely fast. I noticed a couple weeks ago that my battery was going dead after about an hour of usage. I also noticed that my cooling fan in the laptop was running louder than normal. I decided to open Task Manger on my laptop to see what the issue was. I soon noticed that a process called rundll32.exe was using around 25 percent of my CPU. I killed the process and everything returned to normal.
    A few days later, my battery was going dead very rapidly. My cooling fan was on almost constantly and was blowing warm air. I opened Task Manger and sure enough, rundll32.exe was using 25% of my CPU again. I killed the process and everything was fine. It wasn’t long and my laptop was doing the exact same thing as I described before. I decided it was time to get to the bottom of this issue. Here is how I troubleshot what program was using the rundll32.exe and in the process was killing my battery.
    Step One: I downloaded Process Explorer. This is an excellent tool. It is similar to Task Manager but goes into way more depth on the processes and dlls that are running. I extracted the download and then ran Process Explorer as an administrator.
    Step Two: One of the first things I noticed was rundll32.exe was using 23 percent of my CPU again. 
    I right-clicked on the rundll32.exe process and selected properties. I clicked on the Image tab and at once saw the culprit. A utility to monitor and gauge my battery usage, called PwrMgrBkGndMonitor, was draining my battery instead of saving it.
    Step Three: After a little digging around in my installed programs I located a program called Lenovo Settings Dependency Package. PwrMgrBkGndMonitor was installed in the Lenovo Settings Dependency Package.
    I didn’t use this program and decided I didn’t need it. I uninstalled the program and restarted my laptop. I haven’t had a problem with the rundll32.exe using up my CPU since I uninstalled Lenovo Settings Dependency Package.
    If you are experiencing the same symptoms has stated above and you are running a Lenovo laptop with Windows 8.1, this may be your issue. However, before you uninstall the program I would recommend using Process Explorer. Process Explorer will help you determine the exact program that is giving you issues before blindly uninstalling and killing services. I hope my troubleshooting steps can help you find program is making rundll32.exe use high CPU usage. Let me know in the comments if this helped you!

  • High CPU usage and program slowing down

    Hi. I have helped write a program in AS3 that uses classes. We have 2 frames in our movieclip that consists of an ant moving. We have a class of ants and can create 15 instances of them and the program runs fine with the ants walking around looking for food and going back to a corner that is their nest and going back out again. The ants also respond to mouse movement if the mouse pointer is near an ant.
    If we create more than 15 ants, then the program starts to slow down. If we have 30 ants on the screen, then there is noticable stuttering of the ant movement. The CPU usage on a P4 2.5Ghz Pentium is around 50%.
    Is this normal? or is something wrong?
    I would have thought we would be able to scale up the number of ants easily.
    Thanks
    Trev.

    Hi kglad.
    Thanks for the reply.
    I assume enabling cacheAsBitmap is set in the ant class Constructor, as we have tried that and it has helped, see below. We can now create 30 ants with very slight stuttering.
    We have an  ant class as below.
    public class TAnt extends MovieClip { // lots of code here }
    ant Constructor as below.
    public function TAnt(newX: Number, newY: Number, sW: Number, sH: Number, rCyc: Number) {
                this.cacheAsBitmap = true;
               // more code here }
    // We have implemented a Finite State Machine for the ant behaviour.
    regarding the ants using a loop and using a controller class, I am not sure what you mean.
    We are creating instances of the ants in the Ants.fla file which is in the Action file and add each new ant to an array. See below.
    for (var a = 0; a < nAnts; a++) {
        var newAntX = Math.random() * screenWidth;        // randomly generate ant location
        var newAntY = Math.random() * screenHeight;
        var rCyc = Math.random() * 800;
        var ant = new TAnt(newAntX, newAntY, screenWidth, screenHeight, rCyc);            // create ant
        addChild(ant);                                                   // add ant so visible on screen
        ants.push(ant);                                                 // add ant to array
    So we use an array for looping through the ants in the Ants.fla Action file.
    Is this the way you mean?
    Thanks
    Trev.

  • YEARS-old issue with slow play, 100% cpu usage, and conspiracy theories

    I've had the same issue for YEARS now, with flash videos (like on youtube) and games starting out okay, but after a little while, they just start to stutter and slow way down, while the CPU usage goes up to ridiculous levels. The browser doesn't matter, firefox or chrome, online content or run off the local hard drive. I have the latest flash player, and this has been a problem ever since at least version 9. I'm using XP. I think version 8 never had this issue, but unfortunately all recent games and youtube videos won't run with version 8. Adobe did something with recent versions of flash player that causes this issue now. Google search and you'll see countless threads from people with all kinds of computers with all kinds of specs having the exact same issue.
    There has never been an entry in the Adobe knowledgebase about it, despite the persistence of this problem.
    It's like it's a coverup or something. The more I think about it, the more it reminds me about when the Netscape browser was caught secretly uploading information to their servers and resulting in browser slowdowns. Is flash player doing the same thing? Adobe has already been caught out with spyware-like activities with Photoshop connecting to Omniture through the flash-enabled splash screens that were purposely disguised to look like they were innocently connecting to a user's local system, but in fact connecting to stat and online marketing sites. Is this why this years-old problem has never been addressed in any official way? Now I'm just rambling. I want a fix. It's been years now that I haven't been able to enjoy more than a few minutes worth of flash content.
    At this point, even if Adobe shrugged their shoulders and said "yeah, we know about the problem but we have no idea how to fix it" would be better than nothing at all.

  • Server 2012R2 Windows backup 100% CPU usage and no backup

    Hello!
    I have a problem with two VM´s on a HP Proliant ML350p Gen8, that has Windows Server 2012R2 operating system with Hyper-V role installed.
    Both VM´s are also 2012R2, one is DC/DNS/FILE/PRINT and the other one is Exchange 2013.
    The problem itself is that, when Windows backup (wbengine.exe - Block level backup engine service) inside VM starts, it uses almost maximum CPU resource, so the VM´s CPUs are 100% used. Backup itself is not working, there is no network trafic. Only
    way to get rid of 100% CPU usage is to restart the server.
    When i start backup manually (Backup once - scheduled backup options), it is working and the CPU usage is around 20-30%.
    One VM (DC/DNS/FILE/PRINT) has 2x vCPU and Exchange has 4x vCPU.
    The problem started suddenly, the backup were performing slowly and failed.
    Backups are scheduled on different time. Host level Hyper-V backup of VM´s works without any problem.
    The backup location is Synology DS414 NAS and the servers are set up using iSCSI, for connecting separate backup lun´s for each server.
    The Hyper-V host and both VM´s are patched up-to-date. Ofcourse i have tried a lot of restarts, looking event log, VSSADMIN - cannot find any errors...
    The network setup:
    Hyper-V host has a team of two physical adapters, that is set up with a external virtual switch (shared with management operating system) and used by the VM`s normal network trafic.
    Hyper-V host itself is using separte physcial network card, for connecting with iSCSI to Synology NAS.
    I tried to set up another physical network card on the host and create a new virtual swich, add extra virtual nic to VM`s and use this for iSCSI traffic for Windows backup and it didnt make things better.
    I need to find a solution, because i cannot restart the server every night for the backups to work.

  • High cpu usage and game lag problem

    i have a hp 15 d103 tx
    windows 8.1 64 bit
    inel i5 4200m 2.5ghz
    anti virus installed avast fee antivirus
    im using nvidia 820m geforce 344.75 version  driver
    ram installed 8gb
    im experiencing  huge amount lag in games  and software (autocad)
    whenever i run a game (for eg batman origins)    it run smooth  till 2 or 3 minutes after it lag horrribly
    for sake first im getting 45 frames per second then suddenly frame drop to 13 or even to 10
    i have to press alt + tab to check task manger it show cpu usage 30%
    after that when again i press alt tab to back to game it runs fine for 20 seconds and again lag
    i dont what the problem high cpu uasge
    system idle process sometime shows around 82%
    with 8gb of ram still expericing lag
    this problem is with  all game that i have played and software like photoshop and auto cad
    my cousin own hp 15 r007tx and having same gpu nvidia 820m  game runs for on his laptop without a lag
    is it window 8 problem or something else??

    wow finally got the solution by updating bios
    just updated the bios  from 2.7 to 2.8
    no lag now
    i guess different cpu load gpu switching on off was problem
    but now everything is running good
