One of the Hosting Partners available for Sitefinity hosting is Arvixe.
When you attempt to sign up for a Sitefinity account, the recommended plan is a Personal Class ASP or Personal Class ASP Pro account. Each of these accounts offer no more than 250 MB of memory to a single Application Pool after which the IIS Worker Process will recycle the application.
However, when you look at the system requirements to run Sitefinity v. 4.x or v. 5.x, the minimum memory dedicated to the Application Pool needs to be run at a whopping 500+ MB!
I have discovered that running within this limited memory space for any release of Sitefinity v. 4.x or v. 5.x (any edition) causes numerous problems the least of which is constantly being kicked out of the administrative backend due to worker process recycling. Of course, Sitefinity does not handle this gracefully and puts you in an infinite loop of being locked out of the system due to user concurrency issues.
Therefore, are all of these hosting solutions misleading and false advertising since Sitefinity can NEVER run within these restricted memory spaces or does Sitefinity need to go back to all of their hosting partners and state that only the top tier hosting plans can EVER support any release of Sitefinity?
Will the Sitefinity team ever be able to run within a 250 MB restricted memory space? When performance testing is done, are limits placed of 100 to 200 MB on the Application Pool to monitor and watch for how many times the worker process recycles while performing day-to-day administrative content operations in Sitefinity?
