I decided put 2.4 on my laptop. After getting config issues seemingly sorted out, still have some things I can't explain. VMware seems to run about 30% slower. X was even sluggish at times. When I'm doing 'nothing', top shows about 67% IDLE and 30% in 'system time'. I notice that the process "kapm-idled" is being counted as receiving alot of CPU time. Now this could make some sense maybe that idled is getting 30% of the time, but then there's the remaining 67% that came up idle.
I shut down X -- then top showed 5% idle and 95% in "kapm-idled" (and 95% system time) which could still make sense but is probably not the output you want to see when your computer is really idle.
So the kapm thing could be a "display" / accounting problem, but the slowdown in vmware/X was real. I ran a WIN Norton "Benchmark" -- comes up reliably over "300" -- usually around 320-350 under 2.2.17. Under 2.4, it came up reliably *under* 300 with typical being about 265".
So...I'm bummed. I'm assuming a 30% degradation in an app is probably not expected behavior? Swap usage is '0' in both OS's (i.e. it's not a run out of memory issue).
