Others have written results for ordinary 386s with plain IDE disk
in the range of 200-500 kB/s. I tried it at my home PC and I got
similar results. 

However, I always thought that those VAX/VMS machines at work were
awfully slow. So I tried iozone there too. It compiled without a
glitch, and gave results in various machines (workstations up to
large VAX-6410s) with various disks (RA type, RF type, other) 
results in the range 15-40 kB/s. 

What does this mean: Are the disks really that slow? Is the VMS
version of iozone different? Is the OS that significant?

Since this threads seems to acknowledge the presence of people
knowledgeable on hard disk, I thought I might as well ask this.

Met vriendelijke groeten, Wim `Blue Baron' van Dorst
