I bet you don't have this kind of request much. I need tuning advice, because my system doesn't use all it's RAM, and I feel like it's a shame.
I'm running FreeBSD 8.1-RELEASE #0 on a quad core Xeon E5450 (3GHz).
System sits on a 1TB drive. /, /tmp, /var are UFS, everything else is ZFS+compression.
