Anoop Sam John commented on HBASE-14613:
----------------------------------------
Ya with CMS, the pooling was any way helpful only. With G1GC and on heap BB
MSLAB pool, there were not much diff? (Ram?)
As this pool gives an effective way for having an off heap kind of memstore, I
+1 we continue to have it.
> Remove MemStoreChunkPool?

> I just stumbled across MemStoreChunkPool. The idea behind is to reuse chunks
> of allocations rather than letting the GC handle this.
> Now, it's off by default, and it seems to me to be of dubious value. I'd
> recommend just removing it.
