Dear Colleagues,

Here is a result of EPICS benchmark (perform.db and timeMeter.adl by Marty
Kraimer) on Force CPUs.

frc40 (MC68040 25MHz)              
scan    scanPeriod      IDLE    TOTAL
1       1.1%            94.8%   98.0%
0.5     2.0%            91.8%   97.5%
0.2     5.4%            83.5%   97.0%
0.1     11.0%           70.4%   97.0%

frc64(MC68060 50MHz)
scan    scanPeriod      IDLE    TOTAL
1       0.9%            94.5%   97.0%
0.5     1.5%            94.4%   98.0%
0.2     4.2%            88.6%   98.0%
0.1     9.46%           77.9%   96.0%

frc604RT(PPC604 100MHz)
scan    scanPeriod      IDLE    TOTAL
1       0.27%           98.4%   99.0%
0.5     0.54%           96.8%   98.0%
0.2     0.88%           95.2%   98.0%
0.1     2.59%           94.9%   98.9%

Ratio of CPU performances estimated from these numbers is,

 frc40:frc64:frc604RT=1:1.3:4.1
