Don't forget that some amount of page faults are normal consequences of using a machine with virtual memory. Page faults alone are not an indicator that you're out of memory or suffering in any way, they just mean that something was requested in vm that wasn't actually in ram, and needed to be loaded. Ask 'swapinfo' or 'top' to see if you might possibly benefit from more ram by reducing paging. --Doug
