>Second, I get the feeling you've got a bit of a bee under your bonnet on this topic, since George Tasker (to name one person) has dismissed your conclusions. However, it's a long way to go from, "fragmentation seems to help in some tests I've done in VFP" to "fragmentation helps most applications most of the time". You'll need to do a (hell of a) lot of testing to establish that - testing that will need to be consistent and repeatable (i.e. the scientific method ;-)) Put some real numbers to your assertions.

What is the basis for your last statement?
