The numbers you report for buildworld time are roughly on par for my 233mhz box here, on a good day. It's a kick-off-the-build, leave-for-work, come-back-after-dinner sort of box. :-) But my point is, that reported speed might not be so far off, for whatever reason. I couldn't tell from your dmesg if you're using ACPI. If not, does enabling it (on a recent -current) help? I've been running into strange situations with CPU throttling on my machines here, though a throttled CPU still reports the right speed for me.... -Cliff L. Biffle
