Build times for autoconf (a fork test), kernel, and perl.
autoconf kernel perl
2.5.65 3845 1641 1348 seconds
2.5.65-mm1 3898 1646 1326
2.5.65-mm2 3895 1582 1312
2.5.65-mm2-anobjrmap 3824 1614 1284
autoconf and perl builds were faster with anon obj rmap.
kernel build was not. kernel build uses pipe more than
autoconf/perl build. Could be the fact there was only
one sample too.
Lmbench pipe latency and bandwidth don't provide an obvious
explanation why kernel build was slower with anobjrmap.
*Local* Communication latencies in microseconds - smaller is better
2.5.65 15.36 ms
*Local* Communication bandwidths in MB/s - bigger is better
2.5.65 64.5 MB/second
I'm running 2.5.65-mm3 now and will watch how kernel build
AIM7 workloads were generally a hair faster with anobjrmap.
