Good evening,
I currently have TDS 1000 Mbps Down and 400 Mbps, no PPPOE. Plugging the computer directly into the Fiber Box directly I get 900 to 970 Mbps consistently. But when utilizing a router, really any router it slows to 300 to 350 Mbps. I have tried Asus RT-AX88U, Linksys Velop, and Netgear Orbi. Which lead me to try Opnsense, after making the switch I love the features but I still cannot reach speeds past 400 Mbps down with speedtest straight from the CLI.
My current setup is a Qotom Intel i5-7200u, 6 Intel I211-AT, 8GB of RAM
I followed this guide here:
https://forum.opnsense.org/index.php?PHPSESSID=do37lppp3v4gidtdjsdl0do4bp&topic=6590.0
My current config settings for loader.conf.local is below. But I still range 350 Mbps to 400 Mbps. Any advice would be appreciated, or just a point in the right direction. Thank you.

That guide is for IPS. What speed are you getting with just the firewall pared down to a minimal configuration?
Bart...
Thank you for the response Bart,
First install, I followed that guide and had IPS enabled and was getting 330 Mbps to 400 Mbps.
I reinstalled to have a clean slate and try again.
First sets of speed tests ranged between 390 Mbps to 425. I then tuned to the following guide.
https://teklager.se/en/knowledge-base/opnsense-performance-optimization/
Which raised my speed tests ranged to 410 to 440.
Got TDS to come out to my location, they were able to get the TDS DSL Action Tech set up to use the fiber with near speeds as if the laptop. The only difference was they put (null) for host, and they put tds for the domain. All the other settings I have dug thru and cannot find a thing different. The Null option does not work with OpnSense so i am going to test on other platforms.
Thank you everyone that read. And thank you Bart for responding.
Just wanted to update,
Discovered a guide to find MTU, which tested and messed round still wasn't working. But ended up stumbling across this guide for peplink, which explains getting the ping method in addition to setting MSS. I am now getting near full speed on OpnSense. I posted the Peplink link below if anyone is facing the same issue.

Thank you for your sharing eminent!!!
I followed your link and throughput went up:
- from 3xx Mbits/s to 470 Mbits/s (setting MTU)
- from 470 Mbits/s to 600 Mbits/s (setting MSS)
Hardware: t620 plus + i340-t4.
