Fitlet2 Slow Download Speeds

[NV43]

Hello everyone,

I've got my Fitlet2 up and running Opnsense 21.1.6 on FreeBSD 12.1-RELEASE-p16-HBSD and for the most part its been working alright.

I'm using Unbound and have the Adguard plugin set up and those seem to be working fine as well. CPU and memory usage are both very reasonable at under 20%.

The issue I'm seeing though is that I'm only getting about 20% of my rated gigabit download speed. I've narrowed the issue down to something with my firewall by connecting a laptop directly to the modem and running multiple tests with speedtest-cli, all resulting in download speeds of 900Mbps+.

Using ssh to get into my instance and running the same speedtest-cli returns anywhere from 10-30Mbps. Nowhere close to my rated speed.

Is there anything particular I should check to determine what could be causing the issue? Most of my settings should be default from the initial install other than configuring Unbound and Adguard.

Any help would be great. Thanks!

EDIT: Disabling Adguard has no impact on my results.
