By default, OptaPlanner uses selectors with cacheType=JIT, which can 
handle 50K entities with 5k values.
If you specifically specify cacheType=STEP|PHASE or use a custom 
MoveListFactory, look into using JIT or MoveIteratorFactory instead.

If that's not the case, what score calculation are you using?
What's the stacktrace?

Use a tool like VisualVM to find out what is causing the problem. See
