chunhui shen commented on HBASE-6466:
-------------------------------------
Some performance test data for reference,
1.test environment ： random writting；400 regions per regionserver；row len=50
bytes, value len=1024 bytes;5 regionserver, 300 ipc handler per regionserver;5
client, 50 handler per client for writing
2.test results:
before, tps: 7.8k/s per regionserver, Flush:10.1MB/s per regionserver
after(2 cache flush handler), tps: 10.7k/s per regionserver, Flush:12.46MB/s
per regionserver
BTW, under above test, we could increase the tps if increase the client
handlers.

> If the KV is large or Hlog is closed with high-pressure putting, we found
> memstore is often above the high water mark and block the putting.
> So should we enable multi-thread for Memstore Flush?
