It also depends on your checksum routine.
Assembly optimised checksum makes a big difference compared to the
standard C routine.
See the related checksum optimisation discussions.

hi,
Is there anybody know lwip reasonable range of speed, such as send and
receive udp pakets? With and without the os, such as psos or ucosII.
I think it depends on your platform/driver. For instance, I reach up
to 600 ko/s (receiving UDP packets) with current Xilinx drivers (on
PPC 405 @ 350 MHz, without OS), but Xilinx will release new drivers
with DMA support, so performance will be increased (probably up to 4
Mo/s).
Regards,
Cedric.
PS : be carefull with IP fragmentation ; it can slow down the speed.
