We have a platform with 500 site collections and over 30000 users. One of the requirements is to list an overview of the sites (on the central site collection:Home page) the logged in user has access to.
The question is if anyone has some ideas on how to implement this, taking performance etc. into account? (Load time)
The info should more or less be available on the fly and not generated at the moment the user lands on the home page.
Any ideas or remarks are more than welcome!
Kind Regards, Wim
