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

[vincent cui]

Hi:

 

I ported ftpd in my lwIP project.. . and found there is received problem

 

Type “get a.bin” in ftp client console, my server works pretty and get 33KB/s uploading

Type “put a.bin” in ftp client console, my server works , but very slow, I trace the code, and found that sequence TCB payload size is 970, 490, 970, 490, 970, 490 ….

 

The key point is that the payload size is small …it seems to be related with lwIP configuration.

 

Anyone know how to go ?
