packet buffers? is that MEM_SIZE?  i got it up to 32K, but it didn't made any difference.

It might not be that it's too slow; another possibility is that it just
doesn't have enough packet buffers to deal with all the other packets as
well as those that are for the lwIP device, and so you start to get
dropped packets and connections.  This should be easy to check by using
the lwIP stats counters.
