There are multiple factors:

  • the type of garbage collector used;
  • collector configuration (e.g. the size of the various sub-heaps);
  • the size and frequency of memory allocations;
  • typical duration of object lifetime.

Java Performance by Hunt et al has some good material on optimizing Java GC for throughput and latency.

If you have a practical problem to solve, using a memory profiler on your program is often a good first step.
