Throughput uCLinux

Hi all,

as an intern I am trying to find out which OS is best for a NIOS II Dev kit. I think uCLinux is a good start for me.... But when I use TCP or UDP, what performance can I get for my ethernetconnection. Here they would like more then 60 Mb/s. Is it possible when I use uCLinux as an OS with protocol to accomplish this? Or should I use the UCOS-II which is delivered witch the webserver example, which is very slow if I may say so. Perhaps it's because of the LwIP stack, I don't know.... Could you help me out here to give some benchmarks of the several OS'es.

My Board is the: EP2S60F672C5 ES

Cheers,

Danny
