When you perform a simulated calculation, you record the results and use them to estimate actual calculation time.
To estimate total calculation time:
Note the times of all the intervals between application log messages generated by SET NOTICE HIGH.
See Table 185.
Use the following calculation to estimate the time for a real calculation:
Total time required for simulated calculation, divided by the first simulated calculation notice interval, multiplied by the first real calculation time interval.
In this example, 43 / 7 * 45 = 276.4 seconds, so the real calculation should take 276.4 seconds.
