smerkerg edited a comment on issue #1407: HBASE-24099 Use a fair ReentrantReadWriteLock for region close lock URL: https://github.com/apache/hbase/pull/1407#issuecomment-610143826 Yep, understood. I was just hoping someone could explain why numbers would consistently get faster with a fair lock policy... or even why a fair lock would get much slower when there is no thread waiting for a writer lock. So it's a +1 from me, for whatever that's worth.
