stack commented on HBASE-10156:
-------------------------------
This patch seems SLOWER again when low number of handlers (<10). It only comes
into its own when many handlers. For example, when 100 concurrent handlers,
does less work finishes the task in 40% less time. Will post writeup and
numbers later.
> Fix up the HBASE-8755 slowdown when low contention
