Fixing bufferbloat with PF and OpenBSD

Contributed by Janne Johansson on 2018-07-04 from the thinning the bloated puffer dept.

In this post, Paul Smith shows how to reduce buffer bloat and improve interactive traffic latencies.

Long time ago, Daniel Hartmeier wrote a nice piece on how to prioritize ACKs and small packets using ALTQ in PF to sustain download speeds on (mostly) assymetric links, but since then PF and queuing has undergone quite a few changes.

To see an example on how the new rulesets should look, and how to score more internet points on speed tests, head over to his article.
