| |
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.
