You want to test using a file at least twice as big as your RAM, otherwise you're just testing your cache. You can see an example of this on the first graph at http://www.iozone.org . Only the far right edge shows the disks speed. web.archive.org shows that same image existed back in 2000 with a modtime of 1999, so it's possible the machine being tested had under 256MB of RAM. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
