I'm looking for informations and statistics about large SharePoint farms. Who runs such a farm? How many users do they have? How many documents do they manage/store? What does the farm architecture look like?
To put it bluntly, what is SharePoint able to manage?
Are you looking for a case study as to SharePoint scalability? Take a look at the SharePoint Server Scalability and Performance whitepaper (http://go.microsoft.com/fwlink/?LinkId=120901) which covers a scenario with 50 Million content items uploaded into SharePoint.
