I'm curious about the processes that I see running. I've found some stuff on Xorg (the second or third most resource hungry process behind my browser and possibly compiz. Several kworker processes often add up to 2-4% of CPU. Migration also can use a lot.

Again, there is no problem. I just am curious about tweaking them for the sake of fine tuning things.

I'm mostly interested in Kworker. What does it do? Can I limit it's CPU drain on resources?

Kworker is a backgrounded kernel process, its a placeholder for other kernel related processes like i/o and timer functions.

there is an open bug report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/88...
(workaround on post #116) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/88...
where Kworker sucks ~100% cpu, 2% seems normal?
solutions seem to range from upgrading kernel to disabling a certain interrupt, gpe13

ps: If you really want a fine tuned machine, ubuntu based distro's are not the way to go. You may want to check out 'Arch' or 'Gentoo'

I've been eyeing Arch for a while now. I'll make that leap some day soon.

if you want to get your feet wet with arch, but not have to do the manual labor to get it working... checkout some of its derivatives:
Archbang
Cinnarch
manjaro
