Re: X much slower in 2.0.24 than in 1.2.13

I noticed this same thing yesterday when benchmarking XFree86 3.2. It
does look like it's potentially a kernel problem; there seems to be a
much higher proportion of system (kernel) time to user time while X
benchmarks like xbench and x11perf are running than seems reasonable,
about 50/50 if xosview is believable. The benchmarks themselves seem to
draw in a way similar to what would happen if they were being run with a
high CPU load on the system, with jerkiness in the drawing.
