I am currently work with the rackspace CloudSites
service as a web host for Sitefinity. I have reviewed and implemented the medium trust hosting modifications. Most everything works, with the exception of the content management (known issue, search for shared hosting medium trust). Unfortunately, I have not been able to get an answer from rackspace.com about when they will officially support ASP.Net 4.0 (other than a beta program).
Anyways on to my issue... The first time I load a page it can take upto 30 seconds to load a page! I have read through a bunch of posts about page caching, and even implemented a rackspace ping for each webpage, every 5 minutes. This didn't do squat, until I set the InMemory cache limit to 295 seconds (web.config).
Am I missing something? This seems silly to have the webserver prod itself to reload each page every 5 minutes. Not to mention resource intensive, and cumbersome to configure.
