Hi,

Last months, I spent a lot of time on microbenchmarks. Probably too
much time :-) I found a great Linux config to get a much more stable
system to get reliable microbenchmarks:

* isolate some CPU cores

you might be interested in cpusets and the cset utility: in theory, they allow you to isolate one CPU without having to reboot to change the kernel parameters:

However, I never did a scientific comparison between cpusets and isolcpu to see if the former behaves exactly like the latter.

ciao,
