[lwip-devel] Some lwIP performances...

[Frédéric BERNON]

I will commit this evenning the last https://savannah.nongnu.org/bugs/?19162 
fix (I will send the last patch file before).

During my tests, I have try to evaluate which max bandwidth I can get in 
output, with UDP on socket layer. The test send full UDP datagrams (1458 bytes) 
on a 100Mbps/Full Duplex Ethernet interface.

With the patch I will propose, I can get ~90Mbps (~57Mbps with current CVS 
release). Even, with some tips, I can even got... 98.2 Mbps!!! To get this last 
8.2Mbps, I have replace the pbuf_alloc(PBUF_TRANSPORT, 0, PBUF_REF) by a local 
variable, and remove the pbuf_free. I will propose a next patch for that...

Do you have some performance measures on your targets ?
