stack commented on HBASE-9775:
------------------------------
bq, I've tried it myself (exactly the same approach), but I didn't see a real
difference. Do you see one in your tests?
Minor (Certain allocation hotspots went from 3% to 2.4% in my extreme
allocation test which probably means close to zero diff). I left it in since
on the face of it there are less allocations.
I'll commit this since the rig can be useful. Want to do some comment/javadoc
first though.
