As the original bug reporter, I can confirm this bug is now solved *to me* with Ubuntu 12.04 (unity version 5.14.0-0ubuntu1). When idle, compiz consumes 1% of CPU time and when moving windows and doing other things related to windows management, it consumes about 5%.

[Bug 803943] Re: compiz consuming a lot of cpu
Yes, there are real performance problems remaining in compiz and unity. We're still working on improving that from several different angles. I agree with Bernie that overcrowded performance bugs like this tend to never get resolved. That's because: 1. There are too many people to reach any consensus. So really we need to make the original reporter that sole authority on what works, and everyone who disagrees should log their own performance bugs. 2. People experience performance problems with different root causes. So they subscribe to a common bug and expect their problem will be solved when someone else's performance bug is resolved. Performance bugs are almost always too vague and subjective for everyone to agree. So generally we just keep working on improving performance every way we can, with help from peoples' comments, and eventually/sometimes the original reporter will decide the bug is closed.

[Bug 803943] Re: compiz consuming a lot of cpu
This bug makes it particularly painful to use Google Chrome/Chromium as reported here: http://code.google.com/p/chromium/issues/detail?id=98200 One easy test case: Enable the compiz benchmark plugin (compiz-plugins-extra) Open google chrome with two tabs, one blank the other one pointing to: http://www.lri.fr/~kn/test.html (this is a blank page with a bit of javascript that changes the title of the page every two seconds). right click on the tab with the javascript code and choose pin tab. Now bring the other, non pinned tab in front. After two seconds. the pinned tab starts glowing to notify of the title change in the background tab. While the background tab is glowing, one can see 1) compiz renders at 60 FPS, burning between 15% and 20% CPU (depending on the machine I tested on). 2) strace of compiz shows that it is polling the X server socket at a very high rate (see linked bugreport). I could confirm this on precise, both on my laptop and desktop, both Intel graphic cards. Disabling V-sync does not help. Also this does not happen with compiz launched alone. If compiz is launched alone (just X, xterm, compiz and google-chrome), then compiz stays at a moderate 11FPS when the tab is glowing. ** Bug watch added: code.google.com/p/chromium/issues #98200 http://code.google.com/p/chromium/issues/detail?id=98200 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803943 Title: compiz consuming a lot of cpu To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/803943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I also suffer on this problem on an ultra high end laptop with an i7 processor and a nvidia quadro 1000M (proprietary driver activated) graphics card running a clean install of the latest 12.10 builds. There are always two processes comsuming a lot of cpu: Xorg and compiz. At Idle both use around 3% cpu. If i do somthing, it doesn't matter if it is snapping a window, resizing a window, launch a programm or watch a video: compiz climbes up to 50% (very often) and sometimes even up to 118 for a second. This should not be the case. Disabling Unity plugin does not help very much, and disabeling sync to Vblank results in tearing (although cpu goes down a bit). I hope this bug can be fixed till the release of 12.10, because the Unity interface will be nearly perfect right then. This is a really big performance issue with high importance, because it can make users switch. Compiz and Xorg alone are causing very high CPU usage. KDE actually has a bit better performance concerning moving tasks ans especially snapping (compiz often consumes lot of cpu concerning this). When I play a video in KDE X is about 10% and kwin around 1 or 2 %. In Ubuntu Xorg is about 10% and compiz around 10%. But I have to admit Compiz is making great progress!

[Bug 803943] Re: compiz consuming a lot of cpu
You may want to consider a related problem with the combination Compiz and Clamav. I did an upgrade last week from 10.04 to 12.04. After doing this, I noticed a significant slowdown in the performance, basically it became unusable for work. Looking at system monitoring, Compiz was somewhere in the range of using 50% of one processor, but more significant Clamav (installed from the repositories in 10.04) was using close to or over 100% of one processor. I could fry an egg on the laptop. I killed ClamAv and then removed it using package manager. This improved things instantly, though I must say I still perceive it to be slower than 10.04.

[Bug 803943] Re: compiz consuming a lot of cpu
Okay, so I tried messing around with some options, and here's something that worked for me (on fglrx driver): - The problem goes away when I turn off Sync to VBlank (ccsm, OpenGL section). I don't remember having the high CPU usage while idle, but I did have the usage spikes while dragging windows. On my desktop (Radeon 2600XT), and my laptop (Radeon 4670), turning off Sync to VBlank dropped compiz's CPU usage while dragging windows from 25-70% to around 3-9%. I found the following workaround to be effective for me on both my desktop and laptop to both get rid of the tearing, and : (requires proprietary ATi drivers.) 1. Turn off Sync to VBlank in ccsm. 2. Open up the Catalyst control center, (command: amdcccle) 3. Turn TearFree Desktop on (it's under Display Options) 4. Change the Wait for vertical refresh setting to On, unless application specifies. (I had issues with compiz starting up, and changing that fixed it.) The result will be: compiz running with acceptable CPU usage and no tearing.

I had some success by opening up CompizConfig Settings Manager (Alt+F2, ccsm assuming you have it installed.) and enabling copy to texture I noticed the CPU usage on my machine dropped from a hard 10% to about 2% even with programs open. I still find it odd that compiz's CPU usage spikes when I drag windows or sometimes when I have smooth animations in windows despite having the fglrx drivers installed, since it's supposed to be hardware accelerated.

OK, here's a quick guide to recording a performance profile of compiz that we might be able to use... 1. INSTALLATION sudo apt-get install linux-tools-common Then you also need the package specific for your kernel. You can find out what it is called by running perf. That will tell you what you need. 2. RECORD PERFORMANCE Start this and let it run for a while: perf record -p `pidof compiz` Then stop it with Ctrl+C. 3. CREATE A REPORT In the same directory (where perf record created file 'perf.data'), run: perf report compizperf.txt And attach the file compizperf.txt to this bug. It's quite possible that this kind of simple flat profile won't help us. If that's true then you just need to add the -g flag to the perf record command.

Just to point out, compiz using a constant 5% of CPU time can only be considered good in comparison to compiz using a constant 10-20% CPU time. If there's nothing happening on the screen then compiz should be essentially completely idle and using much less than 1% of the CPU time, if any.

With the rhythmbox window open and rhythmbox playing a song (and the slider slowly moving from left to right), but with the rhythmbox window _NOT_ visible, compiz consumes ~10% CPU constantly (Firefox at full screen, two gnome terminals [top dstack] in front of it). dstack seemed to indicate that waitforvideosync (sp?) is (almost, behind some fglrx calls, and ioctl at the very top) at the top of the stack pretty often. That's expected I guess, but I wasn't sure if ioctl can be used to block a thread, so I unchecked the vsync option in ccsm. compiz CPU usage is now down to ~3% with vsync disabled and rhythmbox not visible. slow scrolling in firefox with vsync enabled: ~50% compiz CPU usage slow scrolling in firefox with vsync disabled: ~16% compiz CPU usage I'm not sure what to think of this.
