Tips on CPU Cycle Hogging/Slowdown after OS X 10.2.2 update - (from some of the latest reports on the 10.2.2 feedback page here)
(added 11/14/2002)
" I too have experienced the extreme slowdown of my G4 quicksilver when leaving it running. To try to alleviate the problem I ran the Disk Permission Fix, Disk Warrior and Plus Optimizer. Later last night the system was again slowing down, and looking at the CPU Monitor & Processor Viewer did not help eliminate the possibilities, other than to tell me the system itself was taking over (lots of red in CPU Monitor.)
For no other reason than the mouse was extremely slow, I unplugged the Microsoft Two Button Laser Mouse (reverted to the Apple Mouse) then took all the items that involved contextual menus out of play. These were the MS Mouse Helper in the Login Items, the Contactual Menu plug-ins & Application Enhancers of Stuffit, Copy Paste, Grab & Go, Quick Access, and Labels X. These are all the goodies I like to use via the Right Mouse Button. After 6 hours there was no slow down of the system.
I then went back to the MS Mouse, and stuck the Stuffit expander back in the Contextual Menus. As of this writing the Slowdown has not re-appeared. I will continue to slowly put the additions back in to narrow down the culprit. I know this will take some more time, but I thought I'd pass this information along such that others with the same problem might get some relief before resorting to re-installing everything.

Another report noting that addon software (HP printer drivers) may be a factor:

" Mike,
Just sent you an email about the slow down with my iMac 17" G4 800. Ran across a discussion at Apple support. Seems to be a common problem, most people are reporting that HP drivers may be the cause. A lot of all-in-one users, d135 and d145, have removed the printer software and are reporting a fix to the slow down.

Doug's earlier mail on the slowdown follows)
Mike,
...updated 17" iMac 800, everything seems ok after restart. As another iMac user pointed out, I also have the next day SLOOOWWW down until I restart. I usually run Folding@Home 24/7 and have never had a problem. After 10.2.2 when I come to the computer the next day, the Dock essentially freezes for a few seconds and then moves and refreezes. This stop and start activity is throughout the finder and applications. I ran process viewer and it didn't really seem as if anything was taking over the CPU. I have repaired permissions and that doesn't seem to help. "
I originally suspected 3rd party USB drivers and/or other system addons (I remember past reports on some HP USB printer drivers eating CPU cycles over time - although one reader said he didn't see that problem with 10.2.1 with the HP drivers.)
Hopefully the above may be of help to others that have seen this problem. (I don't have any addons like USB/controller/scanner/printer drivers, etc. installed on my PB G4/800 which has very low CPU usage in 10.2.2, and I suspected 3rd party software may be a factor in some other reports.) The only 3rd party addon I'm running on the PB G4 is ASM (apps switcher menu) which has not been a problem in 10.2.2.
