Anoop Sam John commented on HBASE-14613:
----------------------------------------
As part of the off heaping effort, we have added support for DBB based MSLAB
chunk pool. This seems working fine and we can work with much lesser sized heap
size and better avg GC pause and net GC pause. So IMO we should not remove
MSLAB chunk pool.

> 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.
