ramkrishna.s.vasudevan commented on HBASE-16417:
------------------------------------------------
In my opinion #2 has an impact due to xmx also. If you have 30G then you could
actually have a better GC pattern with more threads and more flushes and GCs.
With 16G your heap is overloaded when you have flushes/compactions happening
frequently as a major garbage generator are from those two operations.
