Description

Hello.

Currently triggering of GC in GMS GC is too naive and should be improved.

Obvious things to implement: 1. Triggering of nursery collection should be dynamically adjusted based on pause time and GC pressure. 2. Triggering of older generations can be based on amount of allocated memory in collection.

IMO, a static threshold for the nursery is OK. It should be something in the order of L2 cache size. The oldest generation should use a dynamic threshold like GC_MS2 does: (memory used) * (constant factor).
