Hi John,

I think the main difference is that I don't use an OS. Ik can reach speed up to 80 MBit/s with UDP. With a modified NIOS II/f and use the lwIP-stack. Is your program based on the simple socket server-example!?

Also set the option optimize most in the NIOS IDE... you get a large footprint of code, but large bandwith...

If you would like my workspace and my NIOS II, just let me know...

Good luck,

Danny
