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.

The box has 16 GB RAM, but not fully used: http://patpro.net/images/mem_rack.png
Sysctl output is available at http://patpro.net/images/sysctl.txt

I've increased some values:


The server is not heavily loaded, but any advice allowing me to benefit from the remaining RAM is welcome.
