FreeBSD 6.3 isn't very suited for your CPU. If your workload isn't completely CPU bound (i.e. if isn't [EMAIL PROTECTED]), you will not only not make use of all 8 CPU cores but will probably get worse performance with 8 CPUs than with 2 CPUs. Upgrade to at least 7.0 and you'll probably need 7.1-BETA2 to maximally use your CPU. But if you don't have much IO contention it's probably not related to your problem. > 16GB RAM You're using the AMD64 version, right? > 3Ware 9650SE-ML / 256MB cache > 14 Seagate 750GB/7200RPM/ST375033ONS SATA drives Which RAID mode?
