Triple speed ethernet performance

Hello, is somewhere some application note like was AN440, where they were tested some types of ethernet applications and table with benchmark test results (in attachment AN440) ? I use DP8384...

What takes time is all the software processing by the IP stack

Yes, every data byte is touched multiple times during processing in the TCP/IP stack. As a result, NIOS based TCP speed hardly exceeds 100MBit/s. The better performance numbers in the application note aren't feasible without hardware acceleration, if I remember right. So besides specialized hardware TCP/IP stack solutions, a faster CPU like ARM SoC should be considered for true Gigabit speed.
