Cheap and nasty: openssl speed (or bench john the ripper) For memory, % mkfile /tmp/128m % repeat 100 gcat /tmp/128m > /dev/null or $ while true; do gcat /tmp/128m > /dev/null ; done (according to taste in shells) while running 'fsstat /tmp 1'. (Note: need to find something that doesn't optimize away the write to /dev/null and doesn't need to do any real work.) Accurate? No. Meaningful? Probably not. Useful enough to compare A vs B? Maybe, provided you don't get into overinterpretation. Realistically, useful numbers only come from testing something that's vaguely relevant to your workload. Expending any effort on getting any other benchmark running seems likely to be wasted. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
