J3355 and i350 performance
-
Running iperf a few times, I'm not seeing the bandwidth I'd expect. Between other devices I'm seeing better performance, so it's clear the bottleneck has something to do with the pfsense box.
Running an ASRock J3355 with an i350 nic.

Anyone have some ideas what to look at next?
