Good that you ran the test but you are still absolutely missing the
whole point of the discussion.
Normally you don't see a change after scrapping the prefetch. There
would only be a meaningful improvement in boot start up after scrapping
the prefetch files if one or more of the files was corrupted. Then
there would be a HUGE difference. No one said it would improve
performance otherwise.
It is just simply a troubleshooting vector you try when you have slow
boot symptoms...

I wasn't having any serious problem with my XP, but the discussion
intrigued me, so I did some tests. I tested boot-up times before
deleting Prefetch, and then after deleting Prefetch (ignoring the
second boot because it was rebuilding the Prefetch files). The
resulting differences were negligible in my case, leading me to
believe that there was nothing wrong with the original items in the
Prefetch folder. FYI, before deleting, there were 99 items in the
folder, and then after, only 54 items. While this was a completely
unscientific test (variables such as programs accessing the Internet
and entering a password), it at least demonstrates to me that for my
circumstances, there isn't any appreciable difference. Just my
observations...

I did it. I did not need a stopwatch to see the difference. A computer
that the user hated to use instantly became normal. Improvement was
better than 10 to 1.
Yes, *in this particular instance* where the prefetch folder was
actually the problem *for a long boot time*, it worked.
Get 10 more PCs at random, time the boot and app load times, clear the
prefetch folder and time boot and app load times again. Let me know
how that goes.
