Vikas Vishwakarma commented on HBASE-17877:
-------------------------------------------
[~larsh] updating in 20-30 mins waiting for final iteration to complete ..
please ignore the above result. My initial observation with JMH is wrong. I
will update the consolidated details in another 1 hour once the test is
complete. Basically a issue with the JMH test that i had written and the byte
arrays used for comparison was static which probably was leading to some
internal optimization. I have fixed that and re-run the tests now I have much
better results but doing two iterations to confirm.
