Re: [lwip-users] how to extend the received payload size

[vincent cui]

I change the value of PBUF_POOL_BUFSIZE from 1024 to 2048. The payload size 
becomes to 1440 ...
It seems the TCB is allocated from POOL.

That sounds like poor fragmentation, either due to dividing application
writes up into MSS-sized chunks that results in a bit left over (the 490
bytes) or as Simon suggested small windows that mean there aren't a lot
of bytes that can be sent at any one time.
