Prasanth Jayachandran commented on HIVE-8121:
---------------------------------------------
IMO, there are many pitfalls of doing microbenchmarking like the one in this
patch.
Lots of them are highlighted in this video by Aleksey Shipilëv (the guy who
leads the development of JMH)

IMHO, we should use JMH for any sorts of micro-benchmarking to get correct and
more accurate results.
