Upgraded from an Intel X520-DA2 to Chelsio T520-CR and iperf dropped from 9.9Gbps to 7Gbps

My pfSense box consists of the following:
Supermicro X10SRL-F motherboard with BIOS 2.0
Intel Xeon E5 2683 v3 CPU 14 cores
32GB of DDR4 2133 RAM
Supermicro 32GB SATA DOM
I ran an Intel X520 in it initially and all was well, but I upgraded over the weekend to a T520-CR and I noticed on the initial boot, that pfSense appeared to update the firmware on it.
The web GUI seems a little choppy at times compared to the Intel NIC. But today I did some iperf testing and found performance to be only 70% of what it should be.
Are there known issues with Chelsio NICs in Supermicro motherboards? Do I need to upgrade the BIOS? (current version is 3.2 and I'm on 2.0)
Do I need updated drivers or firmware for the T520-CR or was that taken care of on the first boot and I noted above?
The firmware will have been updated by the driver if it was older on the card.
You should be able to see it from:
I believe the version in pfSense 2.4.4 is still 188.8.131.52 but there are newer firmware versions available.
You can update it using cxgbetool from the cli. However I would nit expect it to gave made that much difference.
Try testing with
top -aSHrunning to see how the load is spread and what it using CPU cycles.

Yep, I'm on firmware 184.108.40.206.
Turns out that my main issue was that the client I was running iperf on was the bottleneck. I got much better results when another client as seen here:
Ran the test again this morning with top as well using the arguments you suggested. For some reason I was down by about 1 Gbps compared to my previous test. Not sure why.
Maybe I'll put the Intel X520 NIC back in there alongside the T520-CR to do some back to back tests.
Looks like you're running iperf on pfSense which is not really a good test. That could be the limit.
Much better to test between LAN and LAN2 with separate iperf server and client if you can.
