Re: [lwip-users] help! performance of lwip?

[Sathya Thammanur]

The performance depends on various factors - This includes processor
cache size, ethernet device operation mode (DMA vs NO DMA, Interrupts
vs Polled), and ofcourse on the implementation of the netif adapter
itself. I believe that Xilinx performance for lwIP is greatly enhanced
with the new release of the tools.

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).

Cedric.

PS : be carefull with IP fragmentation ; it can slow down the speed.
