Careful there The private chain (Mijin) is ~ 4000 TPS currently with beta Catapult tests. The current public chain is hard capped at around 5 TPS or something I think but is theoretically capable of 15 or so but would need to be unlocked with a hard fork. Once catapult arrives, there should be some sort of measured increase in performance in the public network work once some of those features are folded in.
