[lwip-users] ftp speed is very slow?It is ftpd's problem or tcp's?

[乔崇]

dear Sir:
  I now put http://proff.crowproductions.de/lwipdev.html 's ftpd in my lwip 
system.
  When use point to point net wire,ftpd upload speed is 200~300KB/s.
  When plug in LAN,ftpd upload speed is 0.01K~8KB/s.
So I think,there must be something wrong with my lwip tcp.
The  question is if lwip's receive function need some poll?
I have add a tcp_poll to data pcb,and tcp_output after tcp_write,but no 
improvement.
Help me please!Thank you!
