Axi ethernetlite stress test

I'm using the axi ethernetlite  ip on zynq-m7015 ,linux version 5.4.The IP is working in 100Mbits/sec full duplex mode.

I use  'iperf  -d' in dual testing mode,the tx bandwidth can fetch up to 85 Mbits/sec,but the rx only 35 Mbits/sec,and rx will lose some packets when testing in bi-directional mode.

When in a single direction,both tx and rx can fetch up to 90 Mbits/sec,and do not lose packets.

I wonder if this is due to the ethernetlite  IP performance issues or linux driver issues? How can I deal with?

Hi @Lxx123 ,

I have been trying to check if we have any internal info about stress test for AXI EthernetLite IP, but unfortunately, I could not find any. 

But we do have a few ARs talking about bi-directional performance for MACB driver, and it might inspire you:
