> taskset -c 0 ./python telco.py full Did you see that I just merged Florin's patch to add --affinity parameter to perf.py? :-) You may isolate some CPU cores using the kernel command parameter isolcpus=xxx. I don't think that the core #0 is the best choice, it may be preferred. It would be nice to collect "tricks" to get most reliable benchmark results. Maybe in perf.py README page? Or a wiki page? Whatever? :-)
