stack commented on HBASE-17877:
-------------------------------

First, this is great. Thanks for the work [~vik.karma].

Most compares in hbase are in the few byte range so this should help.

 jmh is best for this sort of compare going forwrad.

On patch, given attribution ("Stolen from Hadoop..class.. i'd say...").  Speed up is just
in how we handle whats left over after we do the long compares?

faster in some cases.
