Chris, have you found any way to set up an automatic prefetch of the forms when the MT is restarted? Seems like a Perl script or something similar might do that. Even if a scheduled one were done each night, that would be better than nothing.

There appears to be a fundamental flaw in the way the mid-tier does caching from the AR server, and the workaround - prefetching the applications/forms, is still something of a band-aid. It also puts a horrific load on the AR server (not mid-tier or db) during the prefetch process, which currently lasts 35 minutes for ITSM 7 minus Asset, per mid-tier web server. WITHOUT prefetching, the consoles (incident, problem, change, etc.) load in up to 1 1/2 minutes the first time they are accessed. After that, it is more like 2-3 seconds. WITH prefetching, the consoles (incident, problem, change, etc.) load in up to 15 seconds the first time they are accessed; after that, it is more like 2-3 seconds. We have seen these response times on two separate systems, both running on more hardware than ARS knows how to use, so I think my assessments are pretty valid. Even if we prefetch the applications, sooner or later we hit some form that did not cache, or log in with a set of permissions that is too different from the prefetch user, and the form takes up to a minute to load even if it is a simple dialog box. It appears that a thorough prefetch is essential to having acceptable mid-tier performance, and I hear that it will be more prominently featured (and documented and supported) in an "upcoming release." I hope so; our testers rated the ITSM 7 application over mid-tier as fundamentally unusable due to the miserable response times until we got prefetching in place. They are still annoyed with it when they are the first user to open any form after a restart on mid-tier.

We are trying to do some demo testing and the web is VERY slow, and not just the initial load. Any other experience(s) to share?
