Choosing the percentage of CPU for each partition

The amount of CPU time that each scheduler partition tends to use under unloaded conditions is a good indication of the budget you should assign to it. If your application is a transaction processor, it may be useful to measure CPU consumption under a few different loads and construct a graph of offered load versus the CPU consumed.
Typically, the key to obtaining the right combination of partition budgets is to try them:
  1. Leave security turned off.
  2. Load a test machine with realistic loads.
  3. Examine the latencies of your time-sensitive threads with the IDE System Profiler tool.
  4. Try different patterns of budgets, which you can easily change at run time with the aps command.
Note: You can't delete partitions, but, you can remove all of its corresponding processes, and then change that specific partition's budget to 0%.
