And i found out that page fault went up the same time as disk activities. May i know what page fault actually do and how do i tune the system to reduce that? DNS is running on P75 FreeBSD 2.1.0 16MB on ep0 with IDE drive. I have a plan to upgrade to P133 with SCSI drive with 32MB. Thanx. rgds, sc khoo
