I have been trying to bolt a standard OpenBSD parse.y based config file onto rtadvd(8) ... [More] for about a year now. I could not do it. The code base is just too weird.

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 ... [More] (mostly) assymetric links, but since then PF and queuing has undergone quite a few changes.
