j3355 and i350 performance
« on: December 02, 2017, 03:45:20 pm »
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.

Code: [Select]
$ iperf -c 10.10.1.1

I've set kern.ipc.nmbclusters to 1000000 and tried hw.igb.fc_setting=0 (reflected in the last test).



Anyone have some ideas what to look at next?
