Sender: owner-freebsd-current@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I really am not so sure what takes the time, but it is not disk I/O. I setup a test machine with 128MB of RAM, a RAID-1 root disk, a RAID-0 8x32KB stripes wide for /usr/src and /usr/obj, on a DPT PM3334UDW (Ultra, wide, differential). Disks are 4GB Barcudas all around. This configuration is capable of 980+ disk I/O per second on the RAID-1 and 1740+ on the RAID-0 array. Starting with a fresh install, SMP kernel current for today, DPT configured with no options, but the performance monitors and a 1 sec timeout hack to catch lost interrupts (new firmware that may be a bit buggy). Top reports (abbreviated): load averages: 7.36, 6.59, 5.06 CPU states: 54.1% user, 0.0% nice, 44.4% system, 1.6% interrupt, 0.0%idle Mem: 11M Active, 17M Inact, 23M Wired, 47M Cache, 8248K Buf, 26M Free Iostat says: tty sd0 sd16 cpu tin tout sps tps msps sps tps msps us ni sy in id 0 1905 771 74 0.0 668 56 0.0 27 0 51 2 20 This is typical over the last hour or so. Anything else I should try? Simon
