For my mid-March non-debug build of main [so: 14] I get,
for example, (.149 is the Rock64 V2.0; .120 is a
ThreadRipper 1950X, both going at the same time
here):

--- 192.168.1.149 ping statistics ---
72 packets transmitted, 72 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.136/0.230/1.903/0.279 ms

--- 192.168.1.120 ping statistics ---
81 packets transmitted, 81 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.211/0.241/0.286/0.013 ms

So, no problem observed.

The root file system is on a USB3 SSD. A removable eMMC is
involved in the booting but no microsd card is present.
