The method commonly used when accuracy is desirable is based on an analysis of
I/O, PC, Communication, and so on, part by part, to obtain load figures for each part and the
complete system.
Another shortcut method to analyze the CPU-load is to work with estimated application
functions of varying complexity.
Forms to be used in your own practice are given in
.
For execution times to use in analyses and estimations of CPU load, see
Data Including Capacity & Performance
. See the manual
3&(OHPHQW
for detailed information
regarding execution times for the individual PC elements.

The performance of redundant processor modules is reduced to 95% in relation to a single
system. Divide all load figures given by 0.95.
