ramkrishna.s.vasudevan commented on HBASE-17048:
------------------------------------------------
The results are consistent. We get 8 to 9 % increase in PE latency when
increasing the size of the allocated buffers. Thanks Duo will see that that
Netty DefaultMaxBytesRecvByteBufAllocator does.
> Introduce a helper class to calcuate suitable ByteBuf size when allocating
> send buffer in FanOutOneBlockAsyncDFSOutputHelper
