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=2048 kern.maxfiles=65536 vfs.ufs.dirhash_maxmem=8388608 regards Claus _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
