Could anyone suggest a !simple! way to generate a bunch of disk operations
(ie reading and writing) under SCO unix. I'm evaluating the relative
performance between 2 SCSI disks, so I don't really need any absolutes!
I thouht some form of script file might be a good way to do it. Since the
machine I will be using is is a new/demo, I don't know which (any) C
compiler is available.
thanks,

I'm evaluating the relative The Byte unix benchmarks have some disk tests. They were posted a while ago and must be around somewhere. I have successfully used them on Xenix/386 Release 2.3.2 and a Sun SparcStation and AT&T Unix running on an Intel System 520. I haven't gotten them to run on BSD and Ultrix systems yet.

The program I've seen used for this purpose is "iobench2" which is a C program that creates, writes, and reads a variable number of files simultaneously. I have a copy on tape somewhere if anyone needs it; I got my copy from the "fiver" bbs system. -- Mike Squires (mikes@iuvax.cs.indiana.edu) 812 855 3974 (w) 812 333 6564 (h) mikes@iuvax.cs.indiana.edu 546 N Park Ridge Rd., Bloomington, IN 47408 Under construction: mikes@sir-alan@cica.indiana.edu
