High CPU Usage.....25% Higher than Ubuntu/Debian [SOLVED]
My Arch 2009.2 x86-64 Gnome install idles at about 25-27% CPU usage.
Similarly configured Ubuntu 9.04 64bit on this same computer idles at about 1%. About the same as Debian 5.0 64bit.
I use the Radeon HD driver on Arch. Ubuntu and Debian use the fglrx driver.
I use Metacity only in Arch, whereas Ubuntu has Compiz installed, but I seldom use it.
xf86-video-radeonhd (1.2.5-1)
Experimental Radeon HD video driver for r500 and r600 ATI cards
Status: Installed
Local Version: 1.2.5-1
Version in the Repository: 1.2.5-1
The Radeon HD description says experimental, but it's in the extra pacman repo.
I believe the Radeon driver is OSS and would be more stable, whereas the fglrx would be more problematic.

37 root 15 -5 0 0 0 S 0 0.0 0:00.00 ata/2How would I further diagnose and work on a solution.....or is this it even worth chasing down.
Having a somewhat high end CPU (AMD quad core 2.5ghz) on this computer compared to my others, may make this more tolerable.
I seldom use high CPU requiring apps, although I do want to get Sun xVM Vbox set up on Arch eventually.
I see from the top command output that it's not just one app using CUP, but spread out over several .......
Are the BSD-style init scripts distros, Arch, Slackware, etc any more or less CPU intensive than a Debian based distro? I wouldn't think so...

Re: High CPU Usage.....25% Higher than Ubuntu/Debian [SOLVED]
Have you tried using the fglrx driver in Arch or using the Radeon HD driver in Ubuntu?

Re: High CPU Usage.....25% Higher than Ubuntu/Debian [SOLVED]

After thinking about this more.......if it was the graphics driver, wouldn't it mostly show up as an increase on Xorg?

Is my logic reasonable here? Anyone knowing otherwise please let me know.
I found searching about this, that in the past, Ubuntu had a kernel bug that caused high idle CPU usage, and a kernel fix corrected the problem.

Re: High CPU Usage.....25% Higher than Ubuntu/Debian [SOLVED]
U P D A T E
Last night, I fell asleep (or was that drank too many beers) while trying to solve an unrelated to this thread problem...monitor signal shutting off.
I remember deleting packages that had anything to do with power management, and got a bit carried away!!!
I woke up to a non functioning Gnome desktop before going to bed.
So this morning, I really wasn't too worried, I'd just use my new Linux skills I've learned from installing and running Arch.
Firefox was still up and running in several windows...Arch Forums, hal, pm-utils, nautilus-power-management.....
I rebooted into the root shell, pacman -Sy, pacman -S (a bunch of packages). Started with hal, pm-utils, nautilus.....
and ended up reloading xorg, xf86-video-radeonhd, gnome, and whatever else I was informed was "hosed" when I tried
to load a package or reboot.
After about an hour, I'm back on my fav new distro, Arch typing this now.
Only difference is my CPU usage is lazily bouncing the guage between 0 and 2% !!!
So to recap what fixed the CPU issue....this isn't something I'd recommend the inexperienced even try, but it had to be the beer.

Re: High CPU Usage.....25% Higher than Ubuntu/Debian [SOLVED]
It's a commonly known fact that you have to match the Arch developers drink per drink in order to properly comprehend Arch Linux. It doesn't take people long to figure this out...
