Hello, Can anyone point me to a tutorial or documentation on how to evaluate a system's performance using vmstat/iostat/etc. Specifically, what are pages paged in/out, page reclaims, the `free list', and how do I tell if my system is requiring more RAM/faster disk bus/etc based on these values. For instance, is it normal to see a value of 200 under `pi', but 0 under `po'? What are page faults, anyway (something to do about a request for memory which is swapped out?) Please email me, since I'm not on this list. Thanks, --dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
