I would also look at power settings in the BIOS and c-state settings in the BIOS and OS as disabling c-states (often enabled by default to meet green/energy star compliance) can make a noticeable performance difference.

I'd be surprised if it did, but now that you mention it, I think that we should probably mention more often that CentOS's default performance policy is power-saving, which will cut maximum performance in half.  Every physical system running CentOS should have run "tuned-adm profile throughput-performance".
