Sure.  I still think however that at this stage it's a much of a muchness.
Modern PC's and disk caching subsystems being what they are, you likely
won't really notice it either way until you're quite far along with this
project.  ;)  (I'm not suggesting you should be willfully stupid of course,
and the mere fact that you write the above indicates you're not, so there's
no problem!)

Sure.  It's of course an assumption that the delay you see is due to disk
I/O... (it may well be, but then again there's lots of possible reasons for
things being slow...)

I know what the full quote is, I continue to be of the opinion that the
point it makes is relevant, it's not worth worrying too much about.  Pick a
strategy that works sufficiently, you can always refactor and improve when
needed.

Good luck,

Walter
