What API are you using?


  #define TCP_WND                         2048

  /* Controls if TCP should queue segments that arrive out of
     order. Define to 0 if your device is low on memory. */
  #define TCP_QUEUE_OOSEQ                 1

  /* TCP Maximum segment size. */
  #define TCP_MSS                         1024

  /* TCP sender buffer space (bytes). */
  #define TCP_SND_BUF                     2048


Try setting TCP_WND and TCP_SND_BUF a bit bigger, eg. 4K.  If you're
interested in performance you'll probably want them even bigger than
that.
