Why is the player so heavy on cpu usage ?

I've noticed playing video's from youtube where the video is
just a still image and the audio plays,
the browser/flash is using 95% of the cpu on my k6-3 @
550MHz.
Clearly, this is the most inefficient media player ever. What
is it doing?

I think it's pretty typical on these boards for people to get worked up when any tiny little hint of a disagreement with Apple's decisions or designs is expressed. There is a post with someone asking about the best way to try to hide the glowing Apple on the lid of his black MacBook and some of the responses were less than cordial.
It's somewhat to be expected here as Apple fanatics are notoriously and rabidly defensive of Apple, and these boards are manned by a lot of Apple fanatics, which of course they do for free and it helps a lot of people.
It reminds me a lot of the console fans who are constantly getting worked up when someone suggests their Xbox is better than the Playstation or vice-versa.
As for the original question, I think it was certainly valid to ask, I wondered that myself. I considered going with a MacBook but when I saw that the MacBook Pro was only slightly heavier I decided to go with the MacBook Pro.
I think the consesus is that it's the metal frame in the MacBook that makes it heavier than you'd expect, but it would also make it a lot more sturdy than laptops without it.

Why does SCHDNEGACTION scheduler job have high CPU usage?

Hi,
In my embeded device(double CPU 1.5 G HZ ) SCHDNEGACTION scheduler job has 90% CPU usage. Why does the scheduler job have so high CPU usage? What is the job doing for?

Hi,
This job is not created by the scheduler. You will have to find out what component creates the job and what exactly it does to figure out why it is using high cpu and what would be the effects of disabling it (which would prevent it from running).
Hope this helps,
Ravi.

Which Is the Best App to Show CPU Usage by App?

ActMonitor by Aeonika ($.99) and System Activity Monitor by Recession Applications LLC ($1.99) are the 2 activity monitors with 5 star ratings. However, the info available for each in the App Store and their websites failed to show whether either measured each open and background apps CPU usage individually.
Knowing that info is the only way we'll get to the bottom of iOS 7.1's higher battery usage.
Does anyone know of a CPU usage monitor that does give us individual app CPU usage?

Why screensaver always causes my macbook 100% cpu usage

screensaver always causes my macbook 100% cpu usage, my mac is ok when i use it, but when i leave it once the screensaver starts to run, the cpu fan start to rock and roll my desk which seems the cpu usage achieve 100%, it will be ok once it come back from screensaver, can someone help me on that? Thank you very much!!!!

Flash player in Chrome high CPU usage

Laptop Specs:
Windows 7 64-bit
Lenovo Thinkpad T410
Intel Core i5 CPU m 520 @2.4 GHz
8.00 GB RAM
This started happening a couple months back (September ish). My laptop run perfectly fine with game play, watching HD movies, running photoshop, etc. It's only when I start up Google Chrome that the CPU usage would spike. It remains under 80% though. With normal internet surfing my CPU usage will teader around 30-40%. When I watch videos via chrome, that's when I have problems. For example, when I watch a "Walking Dead" episode from AMC.com, my CPU usage will spike to 90-100%. After a minute or two my computer will do a hard shut down, as if I pulled the battery out. I'm guessing it is because my CPU is being overworked and over heated. I thought this problem was only with Chrome but when I pulled up the video with internet explorer the same thing happened. I've cleaned my CPU & fan and bought a laptop cooling fan, no help. I've disabled the multiple flash plugins on chrome, no help. I've updated chrome and flash, no help. What should I do? I've read online that this is a common issue. Has there been a solution yet?

Same problem here:
     - x86 Family 15 Model 6 Stepping 5 GenuineIntel ~3000 Mhz.
     - Intel 82945G Express Chipset Family/128MB
     - 4gb RAM
     - Windows XP
The problem is obvious on pages with Flash ads, YouTube (auto resolution), etc. I have the same problem with IE 8; I am guessing, it is not related to the browser.
Ordinary pages with Flash ads keep the CPU at 15%, at least, when not visible; when visible it oscillates from 15% to 90%.
In YouTube the CPU goes to 80% when the video is visible and decreases to 20% when not visible, but it spikes to 30%.
My other, I7, computer has no problem.
Adobe, I hope you will come with a solution. An algorithm should not rely on computer's power.

Why is the Macbook so heavy?

I am waiting for my new macbook to arrive and was just surfing around. Came across this review of a small Asus laptop http://www.pcper.com/article.php?aid=239
What's interesting is that it weighs only 4 pounds and has a built-in modem, card reader, express card port and s-video out. It does have a smaller LCD, but that does not add up to much weight. Given that it has everything the macbook has and also the above extras, what is it in the macbook that weighs so much?
I'm just curious...thanks.

Why does ENET-232 driver use 98% CPU?

I have an ENET-232/4 device running under Windows XP Professional and am talking to it using LabVIEW 6.1. I am taking readings from an instrument every 5 seconds, with a small data exchange (6 byte command, response is about 50 bytes). Everything seemed to work just fine, but when left overnight the computer was very sluggish. The nisdsusr process was using 98% of the CPU time, and it continued to do so until I quit LabVIEW. Stopping the vi, which closed the serial port, was not good enough. I re-started LabVIEW and my vi, and I can see the CPU usage jump up to 12%-14% every time I take a reading, and go to basically 0 in between. This is perfectly fine. Why did this process go to 100% CPU usage and how can I prevent it from happen
ing again? I am using the 1.01 serial device server driver, which is the latest version and is XP compatible (aside from the driver signing issue).

I know this thread is old, but should anyone happen upon it...
This problem (I've had it too) happens when network communication is lost and the serial device server goes into some kind of loop waiting for a tcp ack that never comes back. Something like that. To fix it the port has to be closed that was being used then re-opened. I'm guessing this was your problem when leaving it to run... at some point network communications were lost and the driver went haywire and didn't recover.

High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-(

High cpu usage after a while

Sometimes, after a while, firefox (36.0.4) uses up 1 core of my CPU (is a quad core due to hypertreading). The way it happens is really strange. Many tabs without a problem until suddenly ff decides to floor it. This is alway in the run, not on startup or close. All add-ons need to ask my permissions to be activated, this includes flash.
On close, I ordered ff to clear all history and cookies.
Notes that could be important (The behavior encountered while using it. This varies from time to time):
opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
==> The above seems odd
- Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".
==> The above seems pretty odd
- When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
==> The above looks like that there is definitely something wrong here
This last one has some other things to keep in mind
- When it happens and I close ff, upon restarting it it will ALWAYS ask to close ff. After confirming to close it, it will start and behave normally.
- When killing ff via the task-manager, or other means like powershell commands, restarting it will result in an idle ff even after every tab is loaded again.
I hope this isn't a heisenbug and there is a solution to this, a reboot ff button would be a nice workaround though. I personally think that it must be some routine in the code that decides to go nuts for no reason.
If you need further details, feel free to ask.
Thanks in advance

Tried those before and tried them again. Unfortunately, the problem keeps repeating itself at random times. As said, sometimes it doesn't occur and sometimes suddenly it does. Keep the following things in mind about this, what seems like a heisenbug, behavior.
- opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript

==> The above looks like that there is definitely something wrong here
As stated, a reboot ff button would be a nice workaround. I personally think that something like a tread must get stuck in some sort of infinite loop. Browsing in ff works just fine though. I just don't like the fact that I turns into a "gasoline guzzler".
Again, thanks in advance

DB CPU usage by %

Hi,
Is there anyone know how can we get the CPU usage by %?
I noticed that in the Dbcontrol web page , it able to show the CPU used by %(in the Average Active Session chart), so I
guess there must be some way to query it.
I know V$SYSSTAT, V$SESSTAT ,V$RSRC_CONSUMER_GROUP can be queried to get CPU usage by number,
V$SYSMETRIC_SUMMARY show the usage systemwise, not by Oracle process only.
And V$sessmetric show CPU in number not by %.
Is there any view we can queried to get DB CPU usage by %?
Thanks
Vincent Pek

measure CPU usage which should give you a very good idea about
DB server CPU usage - the implicit assumption being that the
server is used as a db and only as a db.
Could you also please expand a little on the context of your request -
what do want this information for?
Do you want it for a particular statement/process or the whole server?
It would be helpful to know exactly what you're looking for and why.
For example, when you say "by %" - do you mean as a percentage
of the machine CPU usage in total?
In that case, Oracle can't help you, because it only knows about itself,
you have to look to OS tools.

CPU usage when 5 tabs are open and all idling is 35% of 38% total and fan active alot

It seems to me in the last week or so, Firefox has been consuming alot of CPU cycles. This is when my laptop is idling. I know because I monitor by looking at the taskmgr. I see that it takes up 80-90% of the CPU which show as high as 35-40%.

Hi a few days ago I had thought to post it, I have the same computer as the teammatebut a GTX460 @ 4.7 and MPE using colorful II if I use my video in the timeline onlystutters, and a cpu usage of 30 %.
This is normal?
I have two discs, one for OS and one for the project, and the preview footage files.
discs can be problems?

Music store & 100% CPU usage

I've had this problem on my newly built computer, and my older machine. When I browse the iTunes music store, the status bar on the top will often move like it's opening the music store, but it'll do this for a long period of time (several minutes) and iTunes will work, but the music store will not load, and you cannot click the 'X' to stop the contacting of the music store. During this time if you open task manager, iTunes uses 100% of CPU resources. If you close iTunes it still uses 100%. you have to end the process in task manager in order to make it stop. On occasion the music store will work to view maybe one album, but if you search for another album, or click another link it'll do the whole not-responding-100% CPU usage cycle again.
All drivers are up to date and like I said it's done this on two seperate computers of mine on the same iTunes account. I also have a laptop and the music store works completely fine on it. It's only on my desktops that I have this issue.
Some specs on my machine if this will help
Asus motherboard
AMD Athlon XP 4000+ processor
2gb Kingston 184 pin DDR ram
Seagate SATA II 160 GB HD
Windows XP PRO service pack 2
thanks for your help!

I'm only guessing here, but perhaps iTunes is having a conflict with another application. If you are anything like me you probably install your favourite applications on all your computers. As a shortcut to troubleshooting, perhaps consider an application you have installed on the desktops, but NOT on the laptop. Then try uninstalling that application from your desktop computer and test iTunes.

Re: Satellite Pro M70 - High CPU Usage - Low Performance

I sincerely hope someone can help. I do not consider myself really computer illiterate, but this is where my understanding ends and I would truly value all help offered.
I have a Toshiba Satellite Pro M70 of 2 yrs old and I am a definite advocate for Toshiba. However, my operating system is slow. Average day usage with Internet Explorer and Office 2007 is a painstaking process that takes too long. I have had conflicts with Trend Micro Internet Security 2008, which works perfectly.
But starting up the computer takes ages. CPU usage is usually high and System Idle Processes as well. I have reinstalled Windows XP from the Toshiba Boot DVD already 4 times with starting fresh and installing everything time and time again. Each time after getting everything up to speed again, the performance is disappointing.
I have extended RAM to 1,49 GB which made little difference from the original 1/3 of RAM. It seems that something is slowing down the computer, but this is not visable in the processes; other than quite a few svhost.exe processes that take little processing capacity nor CPU usage.
I have used Windows Gold Certified Uniblue Power Suite with a good registry cleaner. This helps a bit, but after a couple of days it seems to get only worse. I have an Intel Pentium M 1.73 GHz processor. Research online reveals that Trend Micro IS 2008 is quite good and demanding little capacity in comparison to competing security packages.
Is this system/software related or could this be a hardware issue?
Thanks in advance to all!

Hi!
This definitively not a hardware issue and I think should try to optimize some Windows settings to make your notebook faster.
At first you should clean the start up folder. Remove all programs that you dont need at start up. For example I dont have programs in the start up folder.
Furthermore you can customize the start up programs in msconfig (start => run => msconfig). There you can disable more programs that you dont need. Its your choice what do disable or enable.
You can improve the performance if you defragment your HDD from time time.
Remove all programs and trial software that you dont need and after this clean the registry. You can use CCleaner as Jimi said.
Try an other antivirus program. Maybe TrendMicro is not full compatible to the software that you use. I use AntiVir.
Bye

CPU usage High

Hi,
Can any one tell me when the CPU usage will go high in oracle? What are the various reasons that affect CPU usage? what are the necessary steps we need to take in order to bring down?
I will be grateful to your answer
With Regards
Boo

CPU usage will increase in Oracle when what you are doing requires CPU resources.
To find of what those things are read the docs.
The steps one uses to decrease CPU utilization depend on what is causing it.
If you want to read the docs you will find them at http://tahiti.oracle.com
If you want someone else to read them for you hire a tutor.

MobileClient.exe holds 100% CPU usage in Citrix

Hi
We have successfully got Mobile Sales 5.0 SP11 working on Citrix but unfortunately, as soon as we have more than 10 people working on it, the application hangs with 100% CPU usage
This server has 4 CPU's and should not max out with so few users.
The infrastructure is set out with the application and the database sitting on different virtual servers with a gigabit connection between them.
The locking point always seems to be on the application server.
Any ideas?
