[Chen]

The TCP's tx bandwidth is greatly affected by the size of
payload for lwip_send.

My test is to send out 1000000
bytes of data as fast as possible (via TCP connection, such as
telnet)

If payload is 100 bytes, it takes only a few seconds to send out all the
data. If the payload is 2048, it takes a loooooooooooong time

Any comment?
