I believe prefetching is only done when a page explicitly requests it
(and that its use is fairly uncommon), so it seems unlikely that it
should have any effect most of the time.

Ugh. Has there been any discussion of disabling this pref? IIRC, it was
recently decided that there were still enough problems with it (and
negligible perf gains?) such that it should remain off for FF3... With
these kinds of "tweak guides" being so widespread and blindly applied, I
think there's an argument to be made that having this pref does us more
harm than good.

Hmm, never heard of this.

Ah, MSDN suggests this is totally bogus:
