Reviewing performance during coding and testing

You should review your performance objectives during the coding and testing phase for your system.

During the coding and testing phases, you must:

1. Refine the internal design estimates of disk and processing resources.
2. Run the monitoring tools you have selected and check the results against your estimates. You might use a terminal network simulator such as Teleprocessing Network Simulator (TPNS) or other tools to test the system and simulate load conditions.
