I wouldn't mind hearing some details on perf. I would imagine a lot of filtering can happen at the true edge via BPF, kernel mods, or otherwise zerocopy mechani

  Ah, for this I'll defer until we have more data. At the moment we have a simple(ish) implementation running at the edge purely within Nginx and a project underway to see how it behaves, gather metrics. That environment gives us a good place in which to control testing, and we can easily compare it to other parts of our code where we already do more trivial request matching (our Page Rules feature). It'll be a couple of months before we're satisfied we know enough to say whether we'll keep it simple or will seek to make it more specialised to our environment. We haven't yet determined how far we're going to go with this... could it replace our WAF? Is it cheap enough for the DDoS layer? If we do go down those paths then it's obvious that yes we'd move the filtering to other places.
