I don't know whether this informal report helps, but lwIP can go pretty darn fast. I could use most of the bandwidth of a 100Mbps network with an ARM7 target with 64K RAM, shoving TCP data. It wasn't a very useful sort of test admittedly :) - it was a dedicated test precisely for seeing the performance. It helps to optimise the header checksum routines. But to be clear, lwIP is designed for low memory use, not performance. You would not expect it to necessarily be as fast as a bigger stack, if you have plenty of memory.
