Zheng Hu commented on HBASE-20751:
----------------------------------
There is a small peak on the avg and p99 curves, because of the balanced
regions, the region server flushed the memstore(s) at the same time...
bq. Seems no difference between master and HBASE-19064 if we do not use sync
replication?
Yes, the QPS & AVG are similar when comparing the master branch with async
replication and HBASE-19064 with async replication. BTW the HBASE-19064 with
sync replication dropped about 13%, we can optimize the sync replication in
phrase#2.
