Firefox 6 has high cpu consumption

Hi,
I have just upgraded from Firefox 5.x to 6.0. I am using Windows 7 32-bit on a Dell Laptop, Core 2 duo, 4 GB RAM.
I have observed that FF seems to consume a lot more CPU than before.
Also, the memory footprint keeps changing rapidly. I don't have a physical memory issue.
The worrying factor is intermittent but unpredictable recurrence of high cpu usage when i open a new site, etc.
Adobe plugin does work but it is a bug CPU hog.
Please help provide a resolution as it seems like going back to 5.x is a better option at the moment since i didn't have much of an issue with FF 5.x.
Thanks,
Anand

Same symptoms as well. Have tried starting in safemode, disabling addons etc. as detailed in solutions elsewhere on this site, but the problem remains. Have completely uninstalled and reinstalled Firfox as well, but no good.
The problem happens instantly whenever I open a link in a new tab or have multiple tabs. The high load (95-100%) does not reduce from this point on and the only solution is to kill Firefox. I'm running XP SP3 on AMD 64 platform.

ITunes 10.6 has High CPU Usage when switched to Mini Player

iTunes has high CPU usage when switched to mini player. The CPU usage goes to 80-100% when the next song is played in Mini Player. iTunes then stays at high CPU usage.
Upon exiting mini player the CPU usage will drop back to the normal 0-5% levels.
This only happens when playing from the main music library; which my library is at 7089 items, 42.04 GB.
When playing from a smaller playlist such as a smart playlist with about 15 songs in it for example, the CPU usage stays low/normal.

Do you have any better luck with that if you update to iTunes 10.6.1.7?
From the notes for the release:
iTunes 10.6.1 provides a number of improvements, including:
• Fixes several issues that may cause iTunes to unexpectedly quit while playing videos, changing artwork size in Grid view and syncing photos to devices.
• Addresses an issue where some iTunes interface elements are incorrectly described by VoiceOver and WindowEyes.
• Fixes a problem where iTunes may become unresponsive while syncing iPod nano or iPod shuffle.
• Resolves an ordering problem while browsing TV episodes in your iTunes library on Apple TV.

High cpu consumption with GRE over IPSEC

Hi all,
After applying a gre over ipsec tunnel on one of our branch office, we get high cpu consumption (average 90%).
Tunnel is applied between Cisco 2851 (C2800NM-ADVIPSERVICESK9-M), Version 12.4(24)T2, (fc2) and
Cisco CISCO2921/K9 Version 15.0(1)M3.
Config of the tunnet is as follow :
- authentication pre-share
- encryption aes 256
- hash : sha
- transform set : esp-aes esp-sha-hmac mode transport
Routing process is eigrp.
Could anyone please help me on solving this issue?

Cool, good start.
Check "show ip traffic" on both sides, it would be interesting to see what's going on.
BTW the CPU usage of top process doesn't add up to 90%, there's a possibility it's traffic rate/pattern + features (IP input and pool manager would suggest that).

Plugin-container in Firefox 4; High CPU and Graphics Switching Problems and Workaround

I recently upgraded to Firefox 4, and unfortunately, I've had many problems running Firefox under OSX on my Macbook Pro.
The first problem I came across was that Firefox is now hardware accelerated. This should be a good thing, but due to the way Apple has implemented graphics switching, Firefox caused the discreet graphics card to be used (as seen with GFXcardstatus)
To prevent this, I went into preferences, and disabled "Use hardware acceleration where available" under Advanced>General.
But my problems didn't stop there. Now, it seems Firefox has decided to run plugins such as flash under a separate process called plugin-container in order to protect the browser from plugin crashes. This is a good idea (I believe Chrome and Safari do the same), but even with hardware acceleration disabled in Firefox and Flash, plugin-container still triggered the discreet graphics.
This would actually be acceptable if plugin-container was terminated after I navigated away from the page with the flash content, but this is not what happens. Instead, plugin-container keeps using the high-powered GPU until Firefox is closed.
At this point, I thought that I'd try to force the computer to only use integrated graphics (using gfxcardstatus), but then I discovered another problem:
The plugin-container process was using large amounts of CPU time when flash content was visible in the Firefox window. Typically, viewing just a static flash ad would cause plugin-container to use about 60% (in addition to firefox using about 20%, that means 80% total). Obviously, this was a battery life problem.
After all of this I think I found a temporary workaround, but there are clearly problems here that need to be resolved by the Firefox developers. There are many non tech-savvy users who are no doubt experiencing poor battery life from these problems.
'''My Temporary Solution'''
1. Disable hardware acceleration in Firefox in Advanced > General
2. Disable hardware acceleration in Flash by right clicking a flash element, clicking settings, and then unchecking "enable hardware acceleration"
2. In about:config, search for dom.ipc and set all boolean values that appear to false. This will disable Firefox's plugin-container process for all plugins.
(At this point, if you restart Firefox, Flash will not work at all)
3. Set Firefox to 32-bit mode by getting info on Firefox.app and then checking the "Open in 32-bit mode checkbox"
4. Restart Firefox. Flash should be working with reasonable CPU usage (I had something like 20% with static flash ads as opposed to 80% before), plugin-container will be no more, and your Macbook will no longer switch to discreet graphics for Firefox or Flash.
'''UPDATE:''' It seems that firefox still sometimes causes a switch to discreet graphics for certain flash elements (video players mostly). Also, I've still seen some cases where flash elements are using large amounts of the CPU, even when they are not in the current tab.
I hope this was helpful to somebody, and if anyone has a suggestion for how to make this workaround obsolete or better, please respond.

Ive downgraded from FF4 to 3.6 at this point. The CPU usage is out of control on OS X.

Z87-G45 has High CPU Usage from "System Interrupts" from USB EHCI#2

After install of Z87-G45 Board and associated drivers the CPU was being consumed by high System Interrupts. I finally tracked this down to the device named Intel(R) Series/C220 Series USB EHCI#2 - 8C2D device. When I disable this in device manager the high cpu immediately drops to 0.1% or less and when I reenable it the CPU consumption goes back to 50% of one core of an i5-4670K under Windows 7 64-bit Of course disabling it turns off most of the USB 2.0 ports.
I have unplugged all USB2.0 headers from the board, updated bios to 1.5, updated the device driver from 9.4.0.1017 to 9.4.0.1025 (7/31/2013), installed the new Intel ME 90 driver pack released on 10/29 and none of this has helped.
Is this a faulty board or is there something else to try?

It was a motherboard swap not a fresh install.
Hopefully you don't have any other problems. This is the recommended way to go.

Problem solved. For the benefit of others who may run into this kind of problem here is my solution. Look for articles on "remove unused USB devices" as a guide. You will be surprised how much junk is left installed on your system. Anything ever plugged in will leave garbage behind.
Go to control panel->System->Advanced system settings on left then under Advanced pick Environment Variables at the bottom.
Create a new variable name = devmgr_show_nonpresent_devices and value = 1
logout/reboot
go to device manager and under view menu pick show hidden devices.
Now manually go through and remove all the grayed out devices, especially under the USB controllers section but worthwhile to remove all the old garbage. Reboot when done.
As always make backups before you start.
Good work

Firefox uses high cpu when playing online flash games like farmville in facebook

Whenever i open games in facebook, firefox uses up high CPU. I tried to install older version of firefox, new version everything has the same problem. There could be some compatibility issue with the adobe flash and firefox.
I am sure that some version works well, because i never had this problem before. Yesterday i had to re-install my XP and after re-install suddenly this issue started, which means this can be solved with proper versions of firefox and flash which i used before.
Please help!!!!!!!

After I made sure I was running latest FireFox and Flash, I started disabling add-ons. It appears right now that Flashblock is the culprit, at least for me. If you have that, try disabling it.
Also, most of those Facebook flash games have some serious problems with memory leaks and bad programming. Is your problem specific to Facebook games or all flash games?

What does com.apple.cts.plugin do? It seems to be causing high CPU consumption by UserEventAgent

I have been having some trouble over the last couple of days with UserEventAgent process. It constantly consumes over 100% CPU. This of course results in obvious problems of the unit getting really hot, high CPU fan speed and faster battery drain.
While investigating the root cause, I removed each of the plugins (located at /System/Library/UserEventPlugins/) one by one and restarted the UserEventAgent process (if you force quit the process, it restarts) and each time, observed the impact on CPU consumption.
After a while, I was able to zero down on "com.apple.cts.plugin". If I removed this file from the plugins folder and forced UserEventAgent to restart, my CPU usage went back to normal with no excess heat or high-speed fan.
While it seems to solve my problem, I am left wondering what this plugin really does and if by not having it I am putting my system at risk.
Any help would be appreciated.

I learnt this the hard-way as well. I am not too sure but probably it has something to do with cerification authority or something like that. BTW I am looking for the answer as well.

Latest flashplayer not work well, even the early version in 11x and has high CPU usage

why is it that flashplayer 11x always has a High CPU Usage? detected by NOrton Antivirus

you can't rely on norton antivirus.
but if you check your active processes and directly confirm a problem with flash player 11+, uninstall your current flash player (http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html or http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html) and install an older version: http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html

Safari 3.03 for Mac has high CPU usage usually above 70%

I look at the Activity Monitor and it shows Safari using a lot of CPU % around 70 % and some times near 100%

This High CPU usage is also a problem that has just started recently on my G4/667/1.5Gig Ram with a "Giga" 1.33GHz upgrade running System 10.4.10. My machine has been wonderful for years with this processor. I'm running Safari 2.0.4. When i did the last upgrades to my software I started having some real bad behavior from my mac. High CPU usage in safari (80-98%) for 3-5 minutes then normal like now I'm at 6-10% (Normal)as I type this in Safari. Safari is crashing when I try to open the Apple in store training site! Mail was crashing on my wife's login not mine though. Throwing out her mail Prefs fixed that. The Upgrades that seem to trigger this are Java for Mac OS 10.4 Release 6, Quick Time 7.3.1, GarageBand 4.1.1, iPhoto Update, iTunes 7.5. It sure feels like that last set of upgrades has made a mess of my mac. I suspect the Java update. How do I fix this mess???? [email protected]

High cpu consumption

Hello,
in a Confluence installation, running on cluster of WebLogic Servers 8.1.4, HP-UX, Java 1.4.2, we observe very often the app server processes keeping quite high levels of CPU consumption.
Each process can fully steadily occupy two/three CPUs or more.
We managed to isolate the threads that seem to be responsible for this, the thread stacks look like the following:
"ReplicatedCache" daemon prio=10 tid=018e5a30 nid=163 lwp_id=9303762 runnable [8ce00000..8ce00dc0]

at java.lang.Thread.run(Thread.java:534)
These threads seem to be waiting to lock an object, but they are constantly in "runnable" state.
Waiting AND Runnable at the same time. Not surprisingly, the eat up CPU clocks.
Any help is appreciated.
Thanks

Unfortunately I don't have the full dump anymore.

NSAPI plugin has high CPU utilization on Sunone web server 6.0 SP5

Hi,
I am running WL 6.1 SP3 with pluginProxy SP03 on Sunone web server 6.0SP5 on Solaris.
Seeing very high CPU utilization with 3 threads running wl_proxy (about 33% each).
Any latest NSAPI pluginproxy patch I can use to fix this?
Walter

I'm having the same problems as all the above posts. I run a colloborative tool which uses IPlanet as a directory server and I receive the Event ID:25 Source: WebServer 6.0 error as well as Event ID:0 Source:https-admnserv6.0 which gives "the local computer may not have the necessary registry information or message DLL files to display messages from a remote computer". I have 3 servers built and all exhibit the same errors.

Cause of high CPU consumption

I created the following test setting:
CREATE TABLE test_p (
        id           NUMBER
      , rand         NUMBER
      , id_pad         VARCHAR2(100)
      , vc_pad          VARCHAR2(50)
) NOLOGGING;
INSERT /*+ APPEND */ INTO test_p (
      id
    , rand
    , id_pad
    , vc_pad
SELECT rownum
     , trunc(dbms_random.value(0,5000))
     , rpad(rownum, 100)
     , rpad('x', 50)
FROM dual
CONNECT BY LEVEL <= 10000000;
CREATE INDEX idx_p_p1 ON test_p (id);
ALTER TABLE test_p ADD CONSTRAINT pk_p PRIMARY KEY (id) USING INDEX idx_p_p1;Now I executed the following statement on several servers (10.2.0.4; most of the servers Solaris 10)
SELECT count(p.rand)
FROM test_p p;One server showed an execution time of 16sec with 13sec "CPU used by this session" and 10sec "db file scattered read". Several retests showed about the same pattern: high CPU usage though there was a low load on the system (24 CPUs and run queue of around 10). I ran the same test on other systems (with less CPUs if this does matter) - the percentage of CPU time / execution time was muuuuch lower on all other systems.
What can be the cause of the high percentage of CPU time?
- because the CPUs are slower on the system with 24CPUs???
- because there might be swaping / Paging???
- because context switches might be more expensive on systems with more CPUs???

MACFLAPS seen only on 1 vlan and also has HIGH CPU HULC LED PROCESS

Hi All,
Their is a weird problem we are having with MAC-FLAPS and HIGH CPU uses. The odd think is when we change the VLAN on the port to a different one then the flapping stops but when we turn it back it starts again. I removed the Vlan from a switch (3750) and the CPU usage returned back to normal even though it was only using it for a printer only (was 50%/30% cpu!).
However the problem now exists with TWO 2960 PCS and 1 2960 POE and they have HULC LED PROCESS at 65%/40% plus CPU usage. There are no STP or HSRP issues on that VLAN however I think it's related to that VLAN. I even backdated the IOS version and reloaded but problem still persists.
What else can I do or is the switch gone (memory leak?). I don't to change all 3 switches so how do I know which switch is the cause as the CPU to be High and only caused due to 1 vlan? ALso when we put something on that VLAN sometimes we get MACFLAPS; although if we change the VLAN the MACFLAPS stop. But the Macflaps are intermittent so I really am not sure what the problem is.

Hello.
Regarding "Hulc led" process - it's a bug; please provide the IOS version you are running.
It's not clear waht issue do you have with MAC flap; could you please provide command/log outputs?

High CPU Consumption when Displaying Animated GIFs

Hi -
Within our application we utilize a lot of the standard AJAX loading icons to indiciate that data is downloading/loading. What we've noticed, however, is that when animated GIFs are being displayed they are consuming between 5 and 8 percent of the CPU. I've confirmed it's definitely the GIF that is causing the CPU usage to increase so dramatically.
Has anyone else experienced this? Do you have work arounds? Does anyone have any idea why performance is so bad on this?
Does using an SWF instead help?
Thanks.

Hello Steve.
Although I'm not really sure what you mean by "content plugins dialogue", you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.
