The June 1990 ACM Computer Architecture News contains the article "IOStone: A Synthetic File System Benchmark" by Park, Becker, and Lipton. They report the results of their benchmark on a diskfull and a diskless Sparcstation, a Sun 3/80, a Decstation 3100, a NeXT, a Sun 2/120, a Vaxstation II, an Apollo DN3000, and a Macintosh II. The thing I found interesting was Sun's variable size disk cashe really skewed the results of the benchmark. The diskless Sparcstation outpreformed the Vaxstation, the Apollo, and the Mac. --jtc -- J.T. Conklin UniFax Communications Inc. ...!{uunet,ubc-cs}!van-bc!jtc, jtc@wimsey.bc.ca
