5.10 Measuring Performance
5.10.1 Measuring Performance
The performance measurement facility of the emulator is capable of measuring the maximum, minimum, average and total
execution times and the number of passes for each of up to eight specified sections of the user program, and shows ratios of
time relative to the overall execution time (Go–Break) as percentages and graphically.
Since this facility uses the emulator’s performance measurement circuit to measure the execution time, it does not impede
execution of the user program.
Performance measurement conditions cannot be manipulated during program execution.
5.10.2 Viewing the Results of Performance Measurement
Results of measurement are displayed in the Performance Analysis window.
To open the Performance Analysis window, choose Performance −> Performance Analysis from the View menu or
click on the Performance Analysis toolbar button [ ].
Figure 5.66 Performance Analysis window
The Performance Analysis window shows the ratios of execution time per condition you have set for the most recent execution
of the program as percentages and graphically.
Any unnecessary columns in this window can be hidden.
To hide any column, right-click in the header column and select the column you want to hide from the popup menu.
To view any hidden column, reselect that column from the popup menu again.
