[edit] Integers
Int (the machine word-sized integer type) is faster than the arbitrary precision Integer type. So don't use Integer in critical places, like inner loops.
That being said, the Haskell (or at least GHC's) implementation of Integer is very fast, as far as arbitrary precision arithmetic goes.
