What benefits would I expect to find with a MFS /tmp system? If there >are benefits, would would be optimial settings for a MFS Not sure about "settings", but the basic thing to look for is a reduction in I/O activity as a result of reading & writing /tmp: the purpose of MFS (and similar approaches) is to accomplish I/O avoidance. iostat can help with the measurement. If you could run iostat with a given workoload, and no MFS, then run it again with as similar a workload as possible, but with MFS, that should provide some indication of how well you're doing. david -- David Wolfskill UNIX System Administrator dhw@whistle.com voice: (650) 577-7158 pager: (650) 371-4621 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
