This has been our experience at Resolver Systems. Code that makes
heavy use of function calls, non-exceptional exception handling or
arithmetic tends to run faster whereas the built-in types tend to be
slower.
It makes profiling code for optimisation all the more important
because all your usual assumptions about Python performance tend to be
wrong...
