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 kernel Pipe 2.5.65 15.36 ms 2.5.65-mm1 15.80 2.5.65-mm2 15.21 2.5.65-mm2-anobjrmap 14.11 *Local* Communication bandwidths in MB/s - bigger is better kernel Pipe 2.5.65 64.5 MB/second 2.5.65-mm1 63.3 2.5.65-mm2 65.9 2.5.65-mm2-anobjrmap 65.1 I'm running 2.5.65-mm3 now and will watch how kernel build goes there. AIM7 workloads were generally a hair faster with anobjrmap.
