Duo Zhang commented on HBASE-16890:
-----------------------------------
I think consume method does the main work here so it is reasonable that it
spent lots of cpu time. And the contention, maybe I could use the RingBuffer of
Disruptor to reduce the time spent in critical section. Will try later.
> Analyze the performance of AsyncWAL and fix the same
