Hi Andrew, (just an fyi) I was curious as to what effect some of these aa patches would have on 2.5.7 throughput, so I wiggled.. aa-096-swap_out aa-180-activate_page_cleanup aa-150-read_write_tweaks aa-110-zone_accounting aa-093-vm_tunables aa-040-touch_buffer aa-030-writeout_scheduling aa-020-sync_buffers ..into it any gave it a little spin. At swap, the aa modified kernel won. At disk blasting though, the stock kernel won big. freshboot; time make -j70 bzImage CC=gcc-3.0.3 && procinfo Linux 2.5.7aa (root@mikeg) (gcc gcc-2.95.3 20010315 ) #89 [mikeg.] user : 0:08:02.98 77.9% page in : 549622 nice : 0:00:00.00 0.0% page out: 437908 system: 0:00:50.93 8.2% swap in : 105628 idle : 0:01:25.86 13.9% swap out: 89827 real 8m59.259s aside 6m55.169s gcc-2.95.3 doing make -j90 user 7m54.930s 6m12.100s on very same 384 mb box... sys 0m34.320s 0m25.050s #!/bin/sh # testo # /tmp is tmpfs for i in 1 2 3 4 5 do mv /test/linux-2.5.7 /tmp/. mv /tmp/linux-2.5.7 /test/. done time testo real 3m43.775s user 0m4.850s sys 0m47.460s freshboot; time make -j70 bzImage CC=gcc-3.0.3 && procinfo Linux 2.5.7 (root@mikeg) (gcc gcc-2.95.3 20010315 ) #83 [mikeg.] user : 0:08:04.81 73.4% page in : 606872 nice : 0:00:00.00 0.0% page out: 482386 system: 0:00:50.95 7.7% swap in : 129625 idle : 0:02:04.66 18.9% swap out: 115843 real 9m39.606s user 7m56.300s sys 0m34.570s time testo real 2m7.581s user 0m4.490s sys 0m41.850s - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
