Duo Zhang commented on HBASE-17048:
-----------------------------------
I think usually the initial size should be 4KB or 8KB? And the increasing
should be exponential unless the size is too large. The
{{RecvByteBufAllocator}} is used by netty to create receive buffer. I mean we
could use the same logic for our send buffer.
And if the size too large maybe we could make use of CompositeByteBuf or just
use a list of ByteBuf to avoid copying(can be addressed in another issue).
Thanks.

> The default ByteBuf size is 256B which is too small.
