I was also only aware of the Perl prefetch script. Didn't realize there was a new XML-based one for Mid-Tier 7.x. Is this available for download somewhere or do I need to contact Support?
I have to say that the Perl script never worked very well and like Kyle said, seemed to only speed up load times for the user that is was executed by but for no one else. It sounds like that has been largely corrected but not completely. Every little bit helps though! Thanks, Michael Gould US House of Representatives On 1/18/07, Kyle Whitley <[EMAIL PROTECTED]> wrote:
Is this only for ARS/Mid Tier 7.x and ITSM 7.x ? 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.
