What processor was this run on? (Can I safely assume that you were running in a non-VM environment?)

    Oops, sorry, missed your Q earlier.

    Two socket, 6-core X5660 Xeon @ 2.80GHz.

    I don't know about 'safe' assumptions, but in this case, such an assumption would be correct -- er.. wait, what's a VM again? ;-)

    I am running a numa-aware kernel, w/default policies, V3.13.5, SMP PREEMPT, 1000Hz clock interrupt in 'tickless mode'.

      2 sockets x 6 cores x 2 (hyperthreading) = 24 "processors". Using 9 threads for your benchmark is a really weird choice.
