Hey, folks. I've discussed this with jwb on IRC, but mailing it too to
make sure the results don't get lost. I tested all the recent kernel
builds on my nouveau (9600 GT) desktop and a selection on my Intel
laptop, using gtkperf and x11perf (x11perf at ajax's request) as quick
and dirty benchmarks, and got the following results. gtkperf tracks very
closely with my subjective perception of performance - when the gtkperf
numbers jump, those are the kernels that feel very slow to me. I don't
really perceive the jumps that are unique to x11perf numbers.
It seems pretty clear from these numbers that slub_debug is the biggest
offender for me, according to jwb. I didn't put the results in the chart
for some reason, but on the nouveau machine just like the intel one,
rc5.git1 with slub_debug=- as a kernel parameter gives a fast gtkperf
time - in the 2.4-2.5 range - and 'feels' perfectly fine, that's what
I'm running right now.
