I consider Jason's question as a design level question.  That's
nothing where a profiler can really help.  Of course you can code up
alternatives and measure performance.  But it can only tell you which
version of several is fastest - it cannot tell you how you should
change your design to improve it.

In this case performance bottlenecks are rather in the area of disk IO
and all a profiler can tell you is how much of your time you spend in
IO - but not how to minimize that.

Kind regards
