Thanks for a > tip about the host's side setup for nc test, I will try it too. I retried nc master/slave test with your template and suggested pbuf values. For synthetic (I used tap interface) I got good results with lwIP, but, for real target, nc test passed for 100% master load and no load of slave side only. I got about 2Mbits per second with the DM900 Ethernet driver (that driver is too slow, it uses memcpy() on every 4 bytes arrived or sent), and my board gives only about 15 VAX Mips for RAM startup, and it seemed for me that was normal result. For small TCP packets ("y\n"), I had got good results yes | socat - tcp4::7 ;# some stress tcp stream "tcpecho" test did return "y" very long time, until I did break pipe (^C). Unfortunately, I could not manage "udpecho" using socat as above neither for synthetic nor real hardware. So, my today score for lwIP 1.3.1 is + http_simple + http_sequential + ns_slave_test + tcpecho - udpecho What was your way to test "udpecho"? Thanks, regards, Sergei
