By mistake, mail was sent to Victor instead of speed. I was asking if the benchmark code is specific to intel x86_64. When I am running this tool (performance) on IBM Power machine, results are kind of promising enough as multiple runs of this benchmark tool comes up with the same result and benchmark seems to be stable.

Thanks Victor. I already tried with --fast and --rigorous option. Rigorous spawns twice the number of worker processes. My result was almost same for both options --fast as well as --rigorous.

Oh ok, good.

I will look into third link you have shared. I have one more query. Almost all the time you have discussed about running this performance tool on Intel x86_64 architecture, even i saw your video about how to tune systems to run benchmarks. I am running this benchmark tool on IBM Power machine running ubuntu O.S. So, should I believe the results what I get here on IBM Power machine.

I focused on hardware that I have (access to), so Intel x86-64 CPUs. Sorry, I don't know IBM Power, I don't know how power management is handled on such CPU. Ask maybe on the speed mailing list?
