5.10 Measuring Performance

5.10.1 Measuring Performance
The performance function measures a maximum, minimum, average and total execution time and a pass count in each of up to
eight specified sections of the user program and then shows a time ratio relative to the total execution time (Go–Break)
numerically as percentage and graphically.
Since the performance function uses the emulator's performance measurement circuit to measure the execution time, it does
not obstruct the execution of the user program.
Performance measurement conditions cannot be manipulated during program execution.

5.10.2 Showing the Result of Performance Measurement

Measurement results are displayed in the Performance Analysis window.
To open the Performance Analysis window, choose Performance −> Performance Analysis from the View menu or
click the Performance Analysis toolbar button [ ].
Figure 5.66 Performance Analysis window
The Performance Analysis window shows a ratio of execution time conforming to the conditions you set in the immediately
preceding program execution numerically as percentage and graphically.
The 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 context menu.
To redisplay any hidden column, select that column from the context menu again.
