stack commented on HBASE-14942:
-------------------------------

bq. However when running G1 we're seeing way too many things end up in the old gen that shouldn't
be

So this ain't in the old gen?

So, our G1 profile is worse than it used to be?

+1 on the patch BTW

> The G1 does a great job of compacting, there's no reason to use the BoundedByteBufferPool
when the JVM can it for us. So we should allow turning this off for people who are running
new jvm's where the G1 is working well.
