oprofile results with lmbench
Quoted 3 lines
the numbers don't look right.
Perhaps you fed oprofpp the wrong vmlinux?
Thanks! You are right. I just put a bold message on the page that the results are invalid. I'm leaving the page up in case anyone else recommends changes. I'll re-run the tests.

btw, when using
RETIRED_INSNS(orCPU_CLK_UNHALTED), you should boot the kernel with `idle=poll'. Otherwise, idle time is unaccounted for in the profile and it gets really hard to interpret, and hard to compare runs.
I've added "idle=poll" to my lilo.conf append.
