Hello Frantisek,

I am glad to have seen your email.

I am Michael and the founder of IPFire, so if you have any questions, feel free to reach out.

We have been a very early adopter for anything Bufferbloat and I have been trying to support Dave as much as possible. We have been running some bechmarks and validating that fq_codel as it was proposed and implemented in the Linux kernel works, and the results were obviously overwhelming. Within a couple of releases, fq_codel was enabled by default, and there was virtually no way to disable it any more because nobody ever would want to have slow internet ever again.

I wrote a little blog post:

https://www.ipfire.org/blog/ipfire-2-13-tech-preview-fighting-bufferbloat

And two articles in the German computer magazine c’t in 2013 - how time flies:

https://www.ipfire.org/blog/ipfire-in-c-t-magazine-20-13

It seems that the links are no longer loading to the article for me :(

Since then we have of course migrated to a mix of fq_codel and CAKE and there have been a couple of researchers posting articles on benchmarking various firewall distros where IPFire always scores really well - if not winning - and a lot of that is thanks to fighting Bufferbloat and us being smart in how we arrange our firewall rules.

Of course IPFire is totally free, so give it a try!

Best,
-Michael
