Experimental Physics and Industrial Control System
This was the results of Motorola VME card with EPICS benchmark I posted in june:
mv167(33MHZ) mv177(50MHZ) mv177(50MHZ)
with 68040 epics with 68060 epics*

average on 1 - IDL 33.75% 19%
In comparison with Noboru's measurements for Force CPU:
mv167(33mHz):mv177(50mHz) = 1:2.56 (average on scanPeriod CPU % usage measure)
1:1.78 (average on 1-IDL CPU % usage measure)
Noboru's scanPeriod measure:
> frc40:frc64:frc604RT=1:1.3:4.1
>
Marty Kraimer's (1-IDL) measure:
> frc40:frc64:frc604RT=1:1.2:5.25
I will report the measurements on mvme1604(100mHz) shortly.
