Is 15-20 seconds as stated by OP a normal tempo?
There's maybe some question as to how much of that is the standard pause at trick 1. It's common for declarer and 3rd hand to pause before playing, but after trick 1 is opening leader's first chance to consider the hand as a whole (when he needs longer than the aforementioned players have taken).
