It's generally a lot quicker to investigate this kind of question
yourself using the interpreter & the timeit module. You'll need skills
like these to be able to profile your code to look for actual
performance bottlenecks, generic advice on the fastest of a set of
functions will only get you so far.
Indeed. Another point to take into consideration is the _real_ dataset
on which the functions under test will have to work. And possibly the
available resources at runtime. As an example, an iterator-based
solution is likely to be slower than a more straightforward "load
everything in ram" one, but will scale better for large datasets and/or
heavy concurrent access to the system.
