Subject: [BENCHMARK] fork_load module tested for contest
Date: Thu, 26 Sep 2002 00:42:16 +1000 [thread overview]
Message-ID: <1032964936.3d91cb48b1cca@kolivas.net> (raw)
I've been trialling a new load module for the contest benchmark
(http://contest.kolivas.net) which simply forks a process that does nothing,
waits for it to die, then repeats. Here are the results I have obtained so far:
noload:
Kernel Time CPU Ratio
2.4.19 72.90 99% 1.00
2.4.19-ck7 71.55 100% 0.98
2.5.38 73.86 99% 1.01
2.5.38-mm2 73.93 99% 1.01
fork_load:
Kernel Time CPU Ratio
2.4.19 100.05 69% 1.37
2.4.19-ck7 74.65 95% 1.02
2.5.38 77.35 95% 1.06
2.5.38-mm2 76.99 95% 1.06
ck7 uses O1, preempt, low latency
Preempt=N for all other kernels
Clearly you can see the 2.5 kernels have a substantial lead over the current
stable kernel.
This load module is not part of the contest package yet. I could certainly
change it to fork n processes but I'm not really sure just how many n should be.
Comments?

P.S. Results have negligible differences on repeat testing.
