Save web.config. Terribly slow page load suddenly responds quickly
Apologies if this is the wrong forum for this question.
I have the strangest issue where a save to web.config changes a single problematic page's load time from 30 seconds back down to less than 3.
It only happens on production servers, and its only one page in thousands of vb.net ajax web forms in a site.
Nothing is changed in web.config, its just the saving action that triggers the change.
I am at a loss to troubleshoot, since I can't reproduce the issue on a test/dev site.
Any ideas what is wrong with the page that a save to web.config makes it run properly again?
