As with most java apps ... it depends.  Memory requirements mostly depend on how much work the PSP is doing for the calculations as well as attribute resolution.  Attempting to bulk-sync a group of 1,000,000 members will vary wildly from a group of 5 members.  16GB heap does seem a bit on the high side though.  My recommendation is to watch it & tune according to the needs of your environment.

How much memory does the PSP realtime process really need? I just noticed that the JVM for mine was configured for 16GB and I want to set it for as low a value as I can get away with.
