Firefox 21 CPU usage problems

I made the stupid mistake of allowing Firefox 21 to install and now must be a guinea pig or part of your User Acceptance Testing, well I don't accept.
Since upgrading there is a pattern, Firefox loads and starts to work OK at first, then after several tabs are open and for no apparent reason it starts using a constant 25% of CPU, at the same time no websites work properly, even Google takes 15 seconds to load.
So I terminate the service and reload Firefox, it then starts to work OK for a while but soon starts the same behaviour all over again. No particular site seems to be responsible and it happens over and over.
I also noticed that the memory seems to keep increasing even if I am not loading any new sites or even if I have Firefox in the background.
I am not going to re-install, I lost thousands of structured bookmarks last time that happened.
Why can't you just release software that works.
None of my plugins seem to have any problem, it seems to just be Firefox.
Is anyone else experiencing this?

This is also a problem on Firefox 23. CPU reaches 100% on starting Firefox and when opening a number of tabs, or just a few or one or two. Firefox then locks up and it is impossible to scroll, open or close tabs/windows while CPU is at 100%.
Firefox do not seem to acknowledge that there is a problem here. This started around version 19 and has been getting worse with each subsequent version. Is it simply that Firefox is becoming more resource hungry with each iteration?

Firefox High CPU Usage

I was on the ford.ca site doing one of those 'build & price' routines, which looked to be flash based. Next thing you know, the little fan is whirring like a turbine, output from top indicated firefox-bin pegged at 108% + CPU (not a typo). I get similar behaviour when using Safari and Logmein to access remote hosts.
Host OS and firefox are both up-to-date.
A bit strange, eh?

I can really only guess that due to it being a "flash" site the graphics can become intensive requesting more CPU usage, the reason I say this is because I also have a 2005 MacMini G4 which has 64MB graphics card and 1.5 GHz processor and visiting "heavy" flash sites causes the fan to become increasingly loud whereas on my MacBook Pro and iMac (both 2GHz + Duo Core's) don't suffer that problem. I suppose if anyone else can share an experience visiting flash sites could shed light to where the problem really is occurring.

Serious CPU usage problem

Hi everyone,
I used to have my own kernel running and everything was fine.
Recently, after the cool changes which happend with kernel/udev related stuff in the last months and weeks, and with the "beyond" kernel being available and having the possibility to use software suspend2 an easy way, I thought it would perhaps be better to switch to the beyond kernel package, staying up to date easily and not having to care about wether some update perhaps wouldn't work with my old kernel anymore...
After some minor hassle, I got it working fine and thought, well, runs reasonably well. But then I discovered some strange issues:
* If I boot with the regular kernel, log in to the console, use mplayer to play an mp3/ogg file, I got 22% cpu usage by mplayer, and additional system cpu usage, summing up to only 66% of my cpu is in idle state!
* If I do the same thing with the beyond kernel, it is still around 7 to 8 %, the CPU has a maximum of 87% idle time
* If I start up X and start xmms, without playing anything, even with stock configuration and nothing changed/enabled, xmms will take 12% of my CPU!
* If I run some other things aside (like mplayer), xmms - still being idle! - still uses 4% CPU
* if I actually use xmms, it takes up to 20% cpu
* now mplayer only uses 2% CPU - but still too much for only playing a music file
So I just don't have anything left than scratching my head. What's going on there?
Ford Prefect

XMMS doesn't play nice with today's Linux scheduler. It's old. (I still use XMMS -- out of sheer habit -- and ignore the problem.)

10.1.3 memory/CPU usage problems

I recently migrated from JDev 9.0.5.2 to 10.1.3.0.4 and impressed with the new features and functionality.
However I've noticed the interface seems significantly slower (eg. code insight and simply inserting a new line of code is much slower), and the memory footprint seems to continually grow. Seeing it at >300M is not unusual.
There are also times when JDev seems to simply hang, and when I look a the JDev process in WinXP, the memory usage grows seemingly out of control as well as gobbling CPU cycles. My only option to kill the process. I'm using a 2.6G Pentium, 1G RAM, WinXP Prof and JDK 1.5.0_05.
Are there known problems with JDev's memory/CPU usage, or known options I can turn off to improve performance?
TIA

I don't have the memory monitor extension and have turned off all non-essential extensions but still see the memory-growth problem.
One odd thing I noticed is the JDev process on WinXP grows by 2-3MB each time a breakpoint is hit. I verified that same behavior doesn't exist in JDev 9.0.5.2 for the same project, and happens no matter which J2SE I select for the 10.1.3 project (JDK 1.4 or 1.5) or which runtime VM (hotspot or ojvm).

MSI KT6 Delta LSR SATA to PATA High CPU Usage Problem

Well recently I've switch to my one of my other motherboards on my network to a MSI KT6 Delta LSR, it was working fine after a reformat, but I notice a few problems and that is 100% cpu usage for SATA to PATA, and vice versa, which seems really crazy. Then my network card performance is ISDN speed sluggish, and I tested my line to be working 100% with another mobo. But when I put another NIC on the same mobo it suffers the same speed problems.
Any suggestions? The rig is specs:
Barton 2500+
Antec QuietPower 350W
200GB Seagate SATA HDD
40GB Seagate PATA HDD
ATI Radeon 7500 AIW
Audigy 2 Value
Realtek 8139 NIC
MSI KT6 Delta LSR Mobo
2x512 MB PC 2700 RAM
Pioneer 107D DVD Writer
LG 16X DVD-ROM
56K Modem (A-open)

Shouldn't say what I don't know about SATA, but since I found below, I need ask if VIA 4in1 drivers are installed, preferably while in SafeMode I say:
http://www.google.se/search?q=cache:X6ewgPiIHYcJ:www.qdi.nl/cgi-bin/bbs/YaBB.pl%3Fboard%3DP4I865%3Baction%3Ddisplay%3Bnum%3D1074174096+sata+to+pata+cpu+usage&hl=sv
I recently installed 160g Seagate barracuda 7200.7 drive on SATA port. (I enabled the Bios using Auto) I have a P4I865pea-6al mother board, with two PATA drives . When copying files between the PATA drives on ide ports, to or from, the SATA drive, I notice the CPU usage goes up to 100%, but when copying files from one ide drive (the PATA drives) to another the CPU usage is very low.
Is there a bios setting that will allow me to copy files from the SATA drive to the Pata drives using a small amount of CPU power, found when just copying between the Primary and Secondary IDE drives? I am using Adobe premiere pro, which uses a lot of CPU power, and the high CPU usage of the SATA drive crashes this program? Any help would be appreciated

have you installed the newest chipset- and ide drivers ?

FMS 4 configuration / High CPU usage problem

I am seeing extremly high CPU usage issues with the FMS 4 server. It seems to be a problem with the FMS Edge process? If you start and stop the service, the processor goes back to normal operations.
Looking in the Windows Event logs I am seeing these errors:
Bad network data; terminating connection : bad chunk version 104 on input stream 00000000077A2E80
Also:
Bad network data; terminating connection : (Adaptor: _defaultRoot_, VHost: Unknown, IP: , App: , Protocol: tunnel) : h o s t = % 2 2 % 2 0 % 2 D F O O B A R % 7 C e c h o % 2 0 % 2 2 % 2 0 S h a r e n a m e % 2 2 % 0 A e c h o % 0 A e c h o % 2 0 % 2 2 % 2 0 % 2 0 S o m e S h a r e % 2 0 % 2 0 D i s k % 2 0 % 2 2 % 6 0 i d % 6 0 % 2 0 % 2 3 % 2 2
Can someone shed some light on what might be causing these issues?

Hi
Can you please provide us some little more environment information on this issue, like:
- what were you trying to do when you saw this issue, if there was a live telecast or if that was a simple vod workflow?
- What publisher application were you using to send livestream to FMS?
- were you also doing some kind of recording while doing live streaming??
- In case of live streaming what audio/video encoding and bitrates was there in use?
- how many number of connections were there?
- What amount of cpu and mem usage was there (when you say very high cpu usage).. you can see it using task manager
It will help if you can also share your fms logs (inside fms_install_folder/logs) so that we can see if something abnormal was going on there..

Flash Player High CPU Usage problem

When I used Flash Player on Windows XP, it used 50-80% CPU Usage so my browser was really laggy but when I used Flash Player on Windows 7, it only used 10-20% CPU Usage... It happened when I load same content on a website.and on same PC (I'm a dual boot user), so I think it's not computer specification problem..
Could someone help me? Thanks in advance.

First go to http://www.adobe.com/software/flash/about/ and check that both XP and Vista have the same version of Flash installed. Then check that both have the same video driver version as a more recent driver may mean more hardware acceleration is supported.

Q180 High CPU Usage Problem

My new Q180 is showing CPU usage of at least 40% all the time in the Windows 7 Task Manager. Sysinternals Process Explorer show that this is due to over 25% of Hardware Interrupts happening all the time.
Is anyone else seeing this kind of problem / symptoms?
Solved!
Go to Solution.

I was able to locate and fix the problem yesterday. The problem was in the Realtek ethernet drivers. I disabled the device from the control panel and interrupts went a way. After that I removed the existing driver and re-installed with the one available on Lenovo support site and now interrupts are gone and CPU utilization is 0% when the computer is not doing anything.

MSI FX5500 128Mb 100%CPU usage problem

Hi,
i have a LANPARTY UT nF3 250Gb mobo and a Atlhon 64 1800+ 512ddr and a MSI FX5500 128Mb with Windows XP SP2, and i'm having too much cpu usage(between 70/100%)..the strange part of this is that i'm having this huge cpu usage when system is at desktop without anything runing (programs..games..).. and no.. its no virus/adware/spyware.. because i've format my system and only install windows and mobo drivers(nf3 drivers) and ofcourse nvidia Display drivers nothing else..
if anyone could help me i appreciate because this slows down my computer a little bit.. :S

its weird..because in task manager in processes separator, there is no process using too much cpu, but in performance separator it shows CPU between 70/100% of usage.. i will try to post a screenshot soon as i can to show to you..
btw.. could this be solved or its my graphic card damaged?
tks

CPU Usage problem

I recently acquired another computer. I installed jdev 10-1.2 on the new machine
using a cd, and then copied my java files from the old machine to the new one.
I opened the project file with jdev and compiled and ran it.
The performance is very slow.(I'm using Windows-XP)
When I check out the Windows Task Manager, I see that the CPU Usage is at 100%. Does anyone have any idea what could be wrong?
Thanks-G.

O.K. Here is another dump...it looks slightly different but it's hard to watch for spikes when the thing is steady at 100% ( no spikes )

Plugin-container / Flash Player CPU Usage Problem

Watching Twitch.tv stream and I am constantly having problems where my CPU locks up at 100%.
Was using chrome with this problem also. Was hoping the switch to Firefox would resolve it.
Windows 7
8GB RAM
Phenom II X4 3Ghz processor

Hello and quiet the cause of this problem is momentary launched firefox version is a Beta test and this problem is hovering lately in our Pc `S.te suggest you're frequently updated on our firefox.Te DepNet.com for the promise that this next vercion will be better with all their efficiencies.
Of course I recommend two (2) options.
1.-update plugin Flash player to the latest version.
2.-In when you leave the vercion but suffers of firefox installed.
And apologies if our products caused you discomfort. Do not worry the solution will come soon. =)

CPU usage problems...

hey, all of a sudden i seem to ahve an issue wiht loads. while doing nothing the laods 'idle' from 50-80% per core... this is doing nothing, and makign sure there's nothign runing in teh backgroudn that shouldnt be.
as i t pe this its at 2ghz, and a high load.. any one have any ideas what could be doign this.. its out of the blue, restarted, and its stil doign it.. its fine for a few min then all of a sudden (after the eboot) it starts to go up...
thanks:(

hey thanks for hte quick repley!
well, at first when i got the mbp i did all the updates... as soon as i rebooted after the 003 security update it started to do it. after a few hours i gave up and wipped the system and reinstall (not archive, compelte reinstall). it was fine until today, 2 or so days. i was out getting some dinner when i came back to notice it was at extremly high loads again (and runign hotter obviosuly), espcially for being at idle...
nothing had been installed or anything changed from when i went to eat and came back. it was fine for 2 days, then all of a sudden it started again. i've tried killing the startup items, checking processes and killing everything that isn't essential to the system.. nothing will fix it at all. as im typing this both cores are jumping 50-75%, theres nothing else even runing other then firefox andno weird processes either:(
just got off with apple and they said it sounds like a hardware problem.. though i'll try my best to resolve it before monday morning so i don't lose my machine for days while they are trying to pin point it being serviced.
thx for the help
james
Oh yea, it was ordered through apple.ca, i'm guessing for a replacement i have to send them it back, wait forever, then theyll send the replacement, so i get screwed out of a machine i paid 2500$ for 2 weeks hu? as if th

[AfterUpdate] Psi unresponsiveness and high CPU usage problem

Hi there
I tried to look for a solution of my problem on the web but apparently can't find anything on the topic.

[2009-03-13 16:36] upgraded util-linux-ng (2.14-1 -> 2.14.2-1)
After the upgrade everything seemed to be fine, but just when I try to write to anyone in the chat window of psi, processor usage increases up to about 97% and psi becomes dead. It doesn't react to anything but SIGKILL.
I am using psi-git form AUR.
I have tried to rebuild the package but it didn't work. So for the moment I had to temporarily switch to psi from extra repo. Nevertheless it would be nice if I still could use git version.
Has anyone encountered similar problems? Does anyone know which package is responsible for this strange behaviour? Is it psi itself (I doubt it because before update it was working well and it wasn't updated) or some kde lib?

Applet CPU usage problem

Hi All,
I have a tcp/ip listener that is running in a thread that is munching 100% of cpu. I wait for data in an endless loop but in a thread this can't take 100% cpu...or can it?

If you check for data all the time, it can. If you tell the Thread to sleep for while between each check you'll use less resources.

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. :-(
