For your comparison on Domain/OS running on 400t and 425t (both have 2x210MB
disks and 16MB RAM):

            TIME:     400t (50Mhz 030)     425t (25Mhz 040)

            real         181.8                 110.3
            user         147.5                  74.8
            system        13.7                   8.4

I deleted all the *.out files before running other tests.
