Nicolas Spiegelberg commented on HBASE-7884:
--------------------------------------------
clockfly: thanks for doing the second test to confirm hotspot warmup would not
fix this issue. I'm disappointed in hotspot optimization since this is an
obvious GCC optimization, but that doesn't fix this issue. Sounds like we
should commit.
