No idea what slightly slower means to you, but I can
guarantee you that with indirect string access you
won't even get to 50% of the original speed.

I need direct access to the strings, due to performance
reasons. Therefore I do not mind the updates whenerver
they are required.

This would be unacceptable anyway.

You are referring to the sample which has those
convenient constant length strings. My application
does not work this way, however. I'd have to
have some basic initialisation first in order to
get quicker access later.

I guess most of us have 1 or 2GB installed these days, true?


Don't get me wrong. Your idea would be definitely
worthwhile considering for other applications. But it
just does not fit my current requirements.
