stack commented on HBASE-953:
-----------------------------
Tried with jdk1.7.0b38 (as opposed to the b31 used above) and it held up. Lots
of full GC's but weathered the PE tests w/o OOME. J-D gave my patch a review
and said fine except for some line-lengths which I've fixed.

> Go back and take another look at the Tom White work. We've gotten boost in
> writing and scanning because of J-D work. HBASE-288 looks like it boosts
> sequential reads and perhaps random read a little. Take another look.
