PT_VAX.EXE from SRI [1] says it runs at 10 VUPS on my notebook (1.5 GHz
Pentium M, 1.2 GB RAM).

Sequential test results:

               MIPs       Dhrystones   VUPs
Run 0          7.3         22002       10.2
Run 1          7.3         24752       10.0
Run 2          7.3         24752       10.0
Run 3          7.1         24752       10.0
---------------------------------------------
Average        7.3         24064       10.0

Interleaved test results:

               MIPs       Dhrystones   VUPs
Run 0          7.3         19801       10.2

Run 2          7.3         24752       10.0
Run 3          7.3         19801       10.2
---------------------------------------------
