If I can't make this machine run faster I have to disable filtering
completely. Given that as a choice, it's time to at least try to get
something running in parallel. The single threaded small memory design
is showing its age, going to faster and faster CPUs to use a single
thread design just doesn't scale. And my next target will be the input
logic, big selects suck and the throughput per sockets is poor as well.

I have one more idea, but that one is so odd I'm not ready to even
admit to having such a thought ;-)
