Ok, guys I am unsure whether I am at correct place here - so please help me figure this out.
For me the increased cpu load since upgrade to 12.04 varies from bootup to bootup (I don't know why and what I do differently). I don't feel the system being slower though. I identified the migration processes to eat up the cpu (see below). The cpu load ranges from nearly unvisible to approx. a quarter when looking at the system monitor panel applet (gnome classic mode). It may be that it decreases over time ... but all this stuff is only subjective observations as I don't know how to measure properly. Please have a look at my ps aux output as this shows the relation of cpu time the migration processes use, compared to e. g. banshee I am using for this whole uptime mainly (besides opera): http://pastebin.com/7PXM4WZX nsk@sesta09:~$ uptime 23:22:50 up 2:13, 1 user, load average: 1.48, 1.39, 1.44 Within this booted session I did nothing actively than hearing music with banshee and browsing/emailing with opera, so everyone can see that the migration cpu time is way too high. But I can not tell if those are real cpu cycles or if this is a reporting problem. nsk@sesta09:~$ uname -a Linux sesta09 3.2.0-27-generic #43-Ubuntu SMP Fri Jul 6 14:25:57 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Please ask me for more if something else will help! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995284 Title: High idle load on 64bit Ubuntu 12.04 with 3.2.0-24-generic kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995284/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
