Actually, times varie between runs. It tends to decrease (except for theghc generated binary), so I suppose it is due to OS cache effects. Yet, I consistently observed that, according to "time", hello2 (jhc) runs _faster_ than hello3 (gcc).Something is wrong: how can Haskell be faster than C?
I suspect if you profile you'll find that Haskell's show is faster than C's printf, especially if the appropriate show instance is selected at compile time.
