What does that have to do with my comment? I didn't say say that an RDBMS is faster than a filesystem, just that your statements about them "seeing serious drops in performance when it comes to indexing, filtering, searching etc." are clearly wrong. It seems very clear that it is you who knows some vaguely relevant bit of trivia, but actually have no clue about the subject in general, and try to make up for that in arrogance. Which is, honestly, pretty embarrassing.
