stack commented on HBASE-15513:
-------------------------------

There was, yes. What was it?

So, this issue should be about doing a bit of testing of at least YCSB loadings to see that
enabling the pool is beneficial all around?

> That results in excessive MemStoreLAB chunk allocations because we can not reuse them.
Not sure, why it has been disabled, by default. May be the code has not been tested well?
