Thanks for reply, actually, the problem is that client (may caused by
server)
always flush data before I decode the each packet when buffer is full. Is it
possible I disable data's aggregating and so that I can get FD_READ message
per packet? I means that get each FD_READ by each calling to "send"at server
side.
