Weird, 
How long for a payload of... let's say 1400 bytes?  
How do you measure/calculate the Bandwidth?

  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?

    Thanks for investigating - it should work fine.  More details of what
    goes wrong, and what you do to cause it to go wrong would help.
