I pasted CarbonEvents.h onto itself 32 times to create a 16Mb file with
466K lines. From hitting Open to being able to flick between top/bottom,
the times were:
BBEdit 8 2 seconds
CodeWarrior 9 6 seconds
TextEdit (10.4) 58 seconds
Xcode 2.1 95 seconds
So whatever extra work Xcode is doing doesn't amount to a x6 slowdown
for me, it's more like x1.5 (on a 1.25Ghz/1Gb PB).
I really don't think there's much you can deduce from external timings,
as the cost of this extra work is going to vary depending on the content
of your test case as much as the number of lines.
About the only thing you can say with certainty is that using a general
purpose text engine makes Xcode's editor slower than editors that are
tuned for this type of content.
