It's not very performant by itself, especially since pyre2 isn't
maintained nor really compilableinstallable anymore.
The performance seems to have decreased from 200 req/s to 0.2 req/s when
using 512 threads, and to 80 req/s using 64 req/s.
This might or might not be related,as the CPU doesn't seem to be the
bottleneck.
I will probably add support for host-based rules, matching the
subdomains of such hosts (as for now there doesn't seem to be any other
pattern for first-party trackers than subdomains, and this would be a
very broad performace / compatibility with existing lists improvement),
and convert the AdBlock lists to this format, only keeping domains-only
rules.
