We have a bunch of imx8mm Mini Evk boards. One of our researchers noticed the ping times were averaging around 2.5ms and thinks that's way too high. He has pinged the evk from a pc and also from one evk to another via a Ethernet switch and directly connected with same results.
So just wanted to get thoughts on what might be causing that.
I tried playing with setting
net.ipv4.tcp_low_latency=1 and it didn't appear to make much of a difference.
When I run wireshark I see lots of ARP traffic going on and I suspect it's because of Avahi and other stuff installed.
