@stephenw10
Thank you for you response, please find replies below:Upgraded from 2.7.0 to 2.7.1 i belive. Current one is 2.7.1 last install was the community edition downloaded 2 months ago.
NIC is broadcom Extreme Gigabit Controller on the PC
Intel Gigabit NIC on the pfsense deviceThey are linked at 1000baseT <full-duplex>
-
What type of Intel NICs are in pfSense?
Are there any errors or collisions on any interfaces shown in Status > Interfaces?
-
I have no clue as to what type of intel NIC's are. Aliexpress site doesn't mention the type of Intel NIC's.
Here is the status of interfaces:

I wouldn't believe anything written on that site anyway.
But you don't need to, you can see what the NICs are in the boot logs like:

Hmm, there are some known issues with the early versions of the i225-V but they didn't present just as slowness.
Check the max interrupt rate:

Can you run an iperf test between local interfaces to confirm if it's WAN side only or not?

Hmm, that's not great. That's just going via one igc NIC.
Are you able to test to a different device on another igc NIC rather than to the firewall dircetly? Running iperf on pfSense always shows lower throughput. You can see it's using significant CPU there, one core may be maxxed out.
You should also try using multiple streams in iperf.

@stephenw10
Connected a laptop to the to a PC on a vlan, then moved the PC from a vlan to the same switch as the laptop both getting similar outputs. I'm looking into multiple streams and how to accomplish that, if that gives me similar results, I will come back from work around 2:00am and try to put pfsense to previous version to see if that will make a difference and will let you know. Thank you for your time.F:\iperf-3.1.3-win64>iperf3 -s

Hmm, one of those things must be linked at 100M to get that.
I would want to see the full ~940Mbps with both devices on the same switch in the same subnet.
Then move one to a different subnet so pfSense is routing it and retest. It should still pass that.

Here's what happened, it had nothing to do with pfsense. I updated the windows 10 pc, 2 of them along with laptop with the latest version via windows update. Apparently that update messed with the TCP settings for some reason. Investigating it, I came across this:
windows killing download speed
So I updated the settings via power shellPS C:\Users\pragmaticOcean\netsh int tcp show global
The autotuninglevel variable to normal from disabled
using the command:
PS C:\windows\system32\netsh int tcp set global autotuninglevel=normal
on all 3 of the computers and Viola! back to normal speeds.Thank you for all your help. Hope this helps someone else that has the issue.

Huh, good to know. Thanks for the update!
