How well does OPNsense deal with bufferbloat in a home networking situation? It appears to implement fq_codel for traffic shaping, but not the newer cake algorithm. Test: https://www.waveform.com/tools/bufferbloat

Huh, TIL about bufferbloat.

I run OPNsense (very happy with it) and had a B, so I followed this guide (https://docs.ibracorp.io/opnsense/) and I now have A+.

Do you have any information on fq_codel vs cake?

Cake is to my knowledge a successor to fq codel. here are some helpful links

This and the debacle with Wireguard are the two top reasons that have kept me on OpenWRT.

Debacle with wireguard? Opnsense has wireguard easily available. Also, it's just base wireguard, so you don't have to go through any extra steps of trying to understand / trust other additions on top of it, which is very nice IMO.

I'm referring to the kernel implementation of it, unless you weren't. But I think you likely are, considering it is now in the mainline FreeBSD kernel. But this took more than 2 years after it was mainlined into the Linux kernel[1], and the delay was largely was because of what happened regarding it's initial implementation[2]. That's the debacle I'm talking about.

Any suggestions for a WiFi 6 mesh running OpenWRT?

https://www.waveform.com/tools/bufferbloat?test-id=5115e016-... No problem with bufferbloat using flowqueue-CoDel.

Also no problems with wireguard... Using it to vpn in and also out for some routes to mullvad.

Probably depends how you tune it, just like pfsense
