The TCP window size can be adjusted by changing the define TCP_WND. However,

on ethernet, where TCP_MSS is 1460, it should be set to at least 2920). If
memory allows it, set this as high as possible (16-bit, so 0xFFFF is the highest
value), but keep in mind that for every active connection, the full window may
have to be buffered until it is acknowledged by the remote side (although this
buffer size can still be controlled by TCP_SND_BUF and TCP_SND_QUEUELEN). The
reason for "twice" are both the nagle algorithm and delayed ACK from the
remote peer.

Be careful about setting this too small. lwIP just counts the number
