Setting up the traffic shaper fixed my issue.. but I lost around 300mbps of throughput. Had to keep turning it down to get the result in the screenshot.

Yes, it fixed it. Is this still an issue? Yes. I had none of these issues on 23.7

Lucky! What ONT do you have?

That sounds like a bufferbloat problem. Some setups show that behaviour, especially when upstream and downstream are asymmetric. There is a good test for this here.

It often shows more when a high BDP is present, such when the other side of a connection has a high latency.

I am at a loss as to why this should happen with 24.1, but probably something has changed in the network stack - I cannot tell since I have not updated yet. Sometimes the bottleneck is outside of OpnSense itself, like when the modem or ONT has too small (or too big) buffers.
You can (sometimes) fix this by using a traffic shaper that limits your up- and/or downstream to what your ISP delivers in order not to overwhelm the connection.

Yeah, it's for sure a buffer bloat issue.. Just not sure what changed in 24.1 to begin causing this.

Don't believe it to be an issue with the ONT. I have the same one as in the post here https://www.dslreports.com/forum/r33627113-

Hi, I have a similar problem since the upgrade to 24.1. As soon as I run a larger download via Steam or PSN, the download rate drops from 1gb/s to about 400mb/s and for the remaining network clients the internet breaks down.   

The hardware does not show high CPU or RAM utilization. I am also a bit at a loss as to the best way to proceed.

My setup:
OPNsense: 24.1.1-amd64 FreeBSD: 13.2-RELEASE-p9 OpenSSL: 3.0.13

Hardware: Low Energy Server LES compact 4L (https://www.thomas-krenn.com/de/produkte/rack-server/technisches-datenblatt/frame.only_content/key.21578.html)

CPU type: Intel(R) Celeron(R) CPU J3160 @ 1.60GHz (4 cores, 4 threads)
RAM: 4GB

I am grateful for any tips :)

Glad I'm not the only one! Everything was completely fine before upgrading to 24.1.1.. I've read into having traffic shaping rules in place but would rather not as it was not needed pre-upgrade. Hopefully, someone can comment further on what is causing this. Fingers crossed!

After updating to 14.1 I've begun noticing crazy high latency while my other clients are downloading files. Even running a speed test on my phone over wifi will cause the download and upload latency/jitter to go from 3-4
ms unloaded to over 30ms. Not too sure what to look at as my system doesn't seem taxed at all. As strange as it may sound my biggest telltale sign of this is while playing competitive COD - I go from 10ms to over 150ms when something is being downloaded by another client.

Setup:
Firewall:  N100 DDR5 version. 8GB 4800mhz Samsung RAM. 250GB Samsung 980 pro https://www.aliexpress.us/item/3256804173757529.html

2.5gb switch connected with ethernet to the firewall - Have 2 gaming PCs and unraid server connected to this with ethernet. https://a.co/d/6OAOe3A

Appreciate any suggestions :)
