I am assembling a collection of benchmarks to measure I/O system performance. This work has not progessed past the stage of determining the appropriate set of metrics that should be used to measure I/O performance. I welcome any contributions, suggestions, and words of wisdom or code if you have it.

He told the following, possibly relevant, story: ... With all this physical memory {>100 MB}, we can make the disk cache as big as we like, so whenever we run up against I/O benchmarks, we just define a disk cache large enough to keep us from having to go out to disk. As a result, our machines have screamed through benchmarks. Some people cry, "Foul! That's not a fair benchmark because I can't do that on my VAX" -- to which, of course, we respond, "Right". Then we smile and don't say anything more. -- Richard Morin, proprietor {hoptoad,leadsv,lll-lcc}!cfcl!rdm Canta Forda Computer Lab. +1 415 994 6860 Post Office Box 1488 Full spectrum consulting services Pacifica, CA 94044 USA for science and engineering.
