You are right. Here are the revised numbers.
Once again 25Mhz 386, pcc.
--------------------------------------------------------------------------
Without reg
Dhrystones/sec: 5400 5400 141.14
Dhrystone 2 using register variables
Dhrystones/sec: 5709 5709 176.04
And 25Mhz 486
Dhrystone 2 without register variables
Dhrystones/sec: 30619 30615 239149.07
Dhrystone 2 using register variables
Dhrystones/sec: 31922 31919 271004.16
----------------------------------------------------------------------------
I looked at the other parts of the benchmark which did not use HZ as a
reference for times.
