> IPCUtil.buildCellBlock is used by both server and client. Server provides
> BoundedByteBufferPool for buffers reuse, client code does not do that. This
> results in additional memory pressure on a client side, because buffers are
> allocated on every call to IPCUtil.buildCellBlock.
> My own local tests (with patch) show approximately 8-10% reduction in object
> allocation rate on a client side (with HBASE-15479 as well).
