I used the netperf tool: netperf -t UDP_STREAM -H 192.168.1.1 -- -m 32768 So I was sending UDP packets to the desktop. The resulting speed was about 370 Kb/s. I tried to send the packets to several different computers - with the same result. So the ppc board is the bottleneck in this case. Is there any possibility to improve the gigabit capabilities of the ppc405EX? Is there anyone who achieved a better performance with ppc4xx boards? Thanks!
