100Mbit ethernet performance on embedded devices

2009-08-19 Thread Johannes Stezenbach
Hi, a while ago I was working on a SoC with 200MHz ARM926EJ-S CPU and integrated 100Mbit ethernet core, connected on internal (fast) memory bus, with DMA. With iperf I measured: TCP RX ~70Mbit/sec (iperf -s on SoC, iperf -c on destop PC) TCP TX ~56Mbit/sec (iperf -s on destop PC, iperf -c
