Hello BIGBG,
Are you still looking for a solution to this issue ?
Your question is not so clear: Are you talking about baud rates or are you talking about throughput through your Ethernet connection ?
I have a DE2-115 and it is doing Gigabit without a problem. (I hope you do not have a DE2-70)
As far as throughput is concerned: If you use Altera triple speed Ethernet, the majority of the work is done by DMA transfers, if you want high rates i think this is the way to go.
What can limit the speed it the capacity of the switch or even the PC (and its software).
Another theme is are you using UDP or TCP/IP these parameters also have influence on the maximum throughput.
Best Regards,
Johi.
