Elliott Clark updated HBASE-14984:
----------------------------------
Release Note:
Setting hbase.cache.memcached.spy.optimze to true will allow the spy memcached
client to try and optimize for the number of requests outstanding. This can
increase throughput but can also increase variance for request times.
Setting it to true will help when round trip times are longer.
Setting it to false ( the default ) will help ensure a more even distribution
of response times.
> Allow memcached block cache to set optimze to false
