tuning advice

Hello, 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+co

DSL/ethernet network perf problem with pf

Hello, I'm running a FreeBSD 6.2 on a Tyan motherboard. The board has 3 ethernet ports (fpx0, em0, em1). It uses `pf` to share/protect an internet access over xDSL plugged in fxp0 to 2 LANs on em0/1. When pf is loaded, my transfert rate for a file on the internet reaches about 150-200 KB/s

Thank you all for your help. I've finally found the bottleneck: the onboard PowerMac ethernet port. After verification, changing network cables was not an option, I've used on this connection a cat. 7 network cable. I've connected the em0 port of the freebsd box on a gigabit PCI-X NIC I hav
