The performance you should usually test yourself. Especially, since you probably want some sort of cashing.
But post-filters were specifically designed to be used for expensive operations (and you can order them too to apply in sequence). They should also work distributed, though each shard will need the information separately, so probably a n* requests to the database for updates. I think ManifoldCF also has some security filters and there are might be commercial implementations too. No idea about LucidWorks, did you check their documentations? They are usually pretty good with that. Regards, Alex.
