I'm a convert from newznab to your new project - have been using Johnnyboy's scripts for many moons...and first let me say - this new project is IMPRESSIVE! Let me say again, extremely impressive! The reduce DB bloat, the clean parts, the speed at which it adds... if there was a 'contribute $$' I would click it!
One thing I've never gotten my mind around though is the post processing piece. This seems to tail behind releases quite a bit - I'm running an i7 quad core / 16GB ram / 4 TB server / Percona with modified my.cnf (I dabble in DBA work) with Ubuntu 12.10 server. And no matter what my post processing queue seems to hang @ around close to 200k in queue! I've dedicated 20 threads to it at once and not seemed to be able to keep up with the backfilling/new indexing that is flooding in.
Guess my moronic question would be - What does Post Processing actually do and what does it provide? The releases all seem to be present and as the post processing loops complete and recycle I do not notice any new releases being added.
