I've been experimenting with RACK and BBR. In my environment, they can dramatically improve single-stream TCP performance, which is awesome. But pf interferes. I have to disable pf in order for them to work at all.
Is this a known limitation? If not, I will experiment some more to determine exactly what aspect of my pf configuration is responsible. If so, can anybody suggest what changes would have to happen to make the two compatible? -Alan
