Hi,<BR>
According to our experience on PPC405 + Gigabit Enet, your result is already very reasonable. For UDP transmission, it can be around 400 Kb/s because of the CPU bottleneck (in our case 300 MHz ppc405). If you want to further improve it, a faster CPU is needed to process the TCP/IP stack, or you may buy commercial TCP/IP stack rather than using the free Linux one. <BR>

I used the netperf tool: <BR><BR>netperf -t UDP_STREAM -H 192.168.1.1 -- -m 32768<BR><BR>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.<BR><BR>Is there any possibility to improve the gigabit capabilities of the ppc405EX? Is there anyone who achieved a better performance with ppc4xx boards?<BR><BR>Thanks!<BR><BR>Best,<BR>Lada Podivin<BR><BR><br /><hr />立刻下载 MSN 保护盾，保障 MSN 安全稳定！ <a href='http://im.live.cn/safe/' target='_new'>现在就下载！</a></body>
