The perl script never really worked well for me, and like Axton said I
had to use a no-permission user to get my requester/self service views
to cache correctly. Guess I need to upgrade my midtier.

I believe the prefetch.xml is driven by the permissions of the account
used to perform the prefetch. That's to say that using an admin
account to perform the prefetch will not have as much of a benefit for
non-permission users accessing the system. I configured our servers
to use a no-permission account to perform the prefetch, since that is
the permission base of our end users that access the mid-tier interface.

The only prefetch script I have seen is a perl script not
anything in
xml. I will say that with the perl script and my testing(ITSM 6
and ARS
6.3), load times really depended on privileges of the user that was
used to authenticate to the AR System in the script. Meaning if I
used
an Admin login in the script the admin views loaded quicker than a
view
a support person would receive on initial load of the view. I
experienced similar load times using the perl script in ARS 6.3,
but my
runtime of the perl script was shorter, I wasn't loading as many
forms
as you have. I only ran the script on requester views for self
service.
