Try to disable HTT in bios. It seldom gives you very much, and somtetimes degrades performance. Is it a webserver? If it generates alot of temporary files you can try adding/changing the following in /etc/sysctl.conf: kern.ipc.somaxconn=3D2048 kern.maxfiles=3D65536 vfs.ufs.dirhash_maxmem=3D8388608 regards Claus
