Hardware and Performance / Weird speed issues with Mellanox ConnectX-3
« on: October 20, 2019, 11:12:44 pm »
Hi,
I installed a Mellanox ConnectX-3 10G nic today. The card was recognized after I prompted the system to load the module (I added mlx4en_load="YES" to /boot/loader.conf.local. So far so good.
However, when I ran iperf3 I noticed that I am only getting about 1.4GB/s on the interface. I've tried turning on/off all the hardware offloading settings, but to no avail. Speed doesn't exceed 1.4GB/s. To rule out other issues, I've booted a live CD image of Ubuntu 18.04.3 on the same system and ran iperf3 from there. I was getting about 9.85GB/s - which I expected.
Is there anything that I overlooked in OPNsense? Is it a module issue in FreeBSD?
Thanks!
