To be honest, there is no definitive answer to this question since the
answer is entirely dependent on so many variables. There are two ways to go:

a) Use the way that is most comfortable for you in your development efforts
(the easiest and fastest to develop has some strengths here for maintenance,
etc.).

b) test with both and go with the fastest.

Either way, there are two things to always keep in mind:

1) Write the code so that you can easily and globally plug in a different
method later if you need to without chanaging every source file.

2) Don't assume that one will be so much slower that you must do one or the
other; performance work should be based on actual performance issues found
by benchmarking, not by guessing ahead of time that something is slower....
