BTW, please do look at "vmstat 1" while running the test case
corresponding to your number of processors. It's hard to tell from the
runtime alone whether the patch is fully accomplishing its goal of
reducing wasted cycles. If you see user CPU percent go to 100 and
context swaps drop to a low value, though, you know it's working.
