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?

Prevent windows closing when tabs are open

Safari closes windows without warning even when multiple tabs are open. This is even more of a problem with the Close button just above the Back button (I tend toward mouse vs keyboard control). I know this has been discussed before, but the solutions either aren't currently available (Taboo) or no longer seem to have the warning tool (Safari Enhancer).
Can Safari do this on it's own (issue a warning before closing pages with multiple tabs open)? If so, how? If not, anyone have a solution?
Thanks,
Carl

Hi Carl
3rd party add-on SAFT has a close window warning as one of its many features. This same feature is also available in Safari 3 Beta via the Safari Preferences>Tab panel. Beta 3 could be installed on your MacBook (requires either 10.4.9 or 10.4.10), but not the other machine.
Beta 3 is available here. If you decide to try it, do not use the computer during the install. After the restart Safari 3 will be in your applications folder. If you use any 3rd party items, such as SafariPlus, SAFT, etc. make sure you have the latest version installed. Same with Adobe Reader (8.1) and Flash (at least 9.0.28).
If you decide to uninstall the Beta, there is an Uninstaller in the Installation package. This is the only way to safely revert back to Safari 2.0.4.

High cpu usage when moving application windows

Hello all,
I have two machines with arch installed:
- an eeepc 701 surf/intel gpu(xorg driver) with xfce
- an amd 3800+ X2/nvidia 8860 gt(proprietary driver) with kdemod3(also checked with xfce4)/arch amd64 installed.
I noticed that when i move a window of an application(for example konsole, etc..) too fast i get high cpu usage(30-40 %), when checking with htop.
Is it normal that the X server uses the cpu so much when moving a window??
EDIT: up to now i tested it in a friends windows machine, and it happens exactly the same, so i guess is normal. It seems i need to be informed better about how X works :-)

today i switced back my desktop system to debian unstable and tried to see what the difference is concerning this problem.
I found out that in kde3 the solution to the "problem" is debians kde default configuration about window behaviour.
Especially the one mentioned below :
In debian this is not ticked and this has as a result zero cpu usage when windows are moved.

If it works in a new window then you can drags tabs from the not working window to that new window.
You can also try to close the tabs via Ctrl+W and restore the closed tabs via Shift+Ctrl+T

After Installing Bitdefender 2011 Firefox is very slow and worse when multiple tabs are open

Firefox performs very poorly after I installed Bitdefender 2011. There was no such problem with Bitdefender 2009. When multiple tabs are open, switching between them is not possible until tab contents are completed.

As ninjafox says, the problem seems to be the BitDefender Anti-phishing Toolbar. Disabling this through Tools -> Add-ons and restarting Firefox seems to fix the problem for that session. However, the problem then reappears when the computer is restarted, presumably because BitDefender re-enables the toolbar.
Another way of disabling all add-ons when starting Firefox is to hold down Shift while clicking on the icon (Windows only I think - at least doesn't work on Ubuntu for me).

When using Tab Groups, is less power/memory used or is it the same as when all the tabs are opened in the task bar?

When using Tab Groups, is less power/memory used or is it the same as when all the tabs are opened in the task bar?

it's just another View for your tabs which needs less *space* in the taskbar, but same *memory* of your computer.
exception: if you (re)start FF and restore the last session (with lots of tabs/groups) there is an option in FF-Settings to load the (content of the) tabs only as soon as they are clicked, and not as soon as FF starts. That trick saves memory.

Firefox doesnt load an image when *lots* of tabs are open

Hi,
An old website I created has a problem displaying a very large background image when *loads* of tabs are open (which makes me think its something to do with memory).
An example page of the site in question is:
http://www.southbankcentre.co.uk/about-us
The white background image (which is super large for reasons not to discuss now) will show fine when, say, up to 10 tabs are open. However, if you have loads and loads of tabs open, this image doesn't display/render (even though firebug says it has).
Some info about the image:
http://www.southbankcentre.co.uk/sites/all/themes/southbank-centre/images/template-3-col.png
79.6kb
940px by 23000px (super huge I know)
The problem is when it doesnt load, the copy is hard to read (as you can imagine).
This doesnt seem unique to my computer. It happens to other peoples firefox browsers (and they have slightly different versions and different plug-ins).

I'm not having any problems on that page with over 80 tabs open and the number of tabs shouldn't matter.
Did you check if you can reproduce it with a clean new profile without extensions?
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks

Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Hello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look.

A lot of memory is used when multiple tabs are open

Is there anything that can be done about the insane memory usage in Firefox when multiple tabs are open? I often have 20+ tabs open and the amount of RAM that Firefox uses when I have it open with this many tabs is just ridiculous. As an example of this, I just restarted Firefox after checking the Windows Task Manager. The Task manager said that Firefox was using 1.2 GB of RAM. I did have 32 tabs open, but this seems excessive even for this many tabs. Some of the tabs were image heavy, but none of them had any video in them. I'd think 10 MB per tab of RAM would be plenty to cover these kinds of pages, maybe 20 MB at most. The upper end of that range would be 640 MB of RAM. Instead, it appears to be using an average of 40 MB of RAM per page when this many tabs are open.
Is there anything that can be done to reduce amount of memory being used when multiple tabs are open? It really shouldn't need this much RAM to serve this many pages.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance

Safari warning before quitting when multiple tabs are open?

I'm a rather clumsy typist who often uses Apple+Tab to toggle through my open programs. This works great 99% of the time, but that other 1% is rather frustrating considering that the Q key is right next to Tab.
Apple guys, please implement a pop up/drop down warning when attempting to quit Safari when multiple tabs are open (or at least the option to enable or disable it). I use this browser for work and often have many tabs open, so accidentally quitting the browser only impedes on my workday. I know I should be more accurate, but isn't that what part of progress is? The empowerment of laziness? =)
Thanks for your time, and hopefully we see this included in soon-to-come upgrades!
Oh, and if this feature is already available, feel free to show me the way.

jefftovar,
I created and modified the Safari Keyboard Shortcut
Quit (⌘+Q) command to (⌘ControlQ) by using System
Preferences...>Keyboard Shortcuts.
;~)
Great suggestion! But, the default Quit (⌘+Q) command is still in effect. I've looked about in trying to deactivate it, but can't seem to find it. How did you get rid of yours?

Firefox 12 is very slow to load pages and if two tabs are opening it lags.

Firefox 12 is very slow to load pages and if two tabs are opening it lags. I've tried everything (e.g virus, defrag, I've created a new profile in "run", etc). I've had my router/line etc all checked and after 2 weeks of cleaning/testing etc its all pointing to Firefox as the problem. Please help as it's driving me nuts.

I have the exact same problem.
Not only does it load pages very slowly, sometimes the page will stop for a good 45 seconds and stop loading, only to finish it much later.
Something is wrong with Firefox 12, it shouldn't be this slow.
How is that each version is progressively worse than the one before it?.
Stop releasing so many versions Mozilla, release one that works and build from there.

Hello,
Are the pdf linked correctly in the website? Is this a public website? If yes, please post the link here.

Firefox crashes when i clear recent history if multiple tabs are open, is anyone else experiencing this?

Firefox crashes (hangs, requires me to force close, and then doesn't actually clear the history) when i clear recent history if multiple tabs are open, i do this so i only lose the history and can maintain the tabs i want for the next session.
I have always done this in Versions 3 without an issue, since moving to Version 4 it happens semi regularly. the more tabs i have open the higher the likelyhood of an error
is anyone else experiencing this?
Windows 7 pro sp1
firefox 4
addons: no script, adblock, pterodactl, imagezoom, reddit reveal, java, tinyeye, better privacy.

This happens to me too. OS winXP home.

When I am trying to open multiple tabs by clicking on File- New Tab, no additional tabs are opening i.e. I cannot open multiple tabs in my browser..Please help..

I am unable to use the multiple tabs option in my firefox browser. When I am clicking on File->New Tab no additional tabs are opening..

The Ask Toolbar is causing that in the Firefox 3.6.13 version. Evidently something in that extension isn't compatible with a Firefox security fix. Disable that extension or un-install it.

High CPU usage when graphics card is put at work

I have a 13inch Air with 2GB RAM and 256GB with Windows 7 Ultimate 64bit. All possible updates have been installed.
I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
Has anyone experienced the same or know what could be causing the beavior?
Many thanks

Maybe my initial post was not clear so let me add some clarifications.
I have the problem with Aero disabled
I have the problem on the Apple site which does not have any flash content.
I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
It would be great if someone you also do the test to check the cpu load:
- when playing a 720 mkv
- when dragging a window across the screen
Just open task manager and see if the CPU spikes.
Many thanks!
