I haven't hosted modded servers in many years but a while ago the advice was to avoid (4, 8] GB (might have been 6.5 instead of 8, I don't remember, but the point is there's a dead zone) because of something weird with the garbage collection. I think it had to switch to 64-bit pointers or something. Anyway the worse garbage collection outweighed the memory advantage. I personally never hosted with more than 4gb.

IIRC more memory also increases GC time so after a certain point the GC causes such annoying lagspikes it's often better to play with less.
