These limits are as follows:
1. Number of SharePoint users fewer than 2,000—The number of specifically defined
users in a SharePoint site should not exceed 2,000, or the risk of performance degradation
arises. If more users are needed, Active Directory group membership can be
used to scale the number of users to the tens of thousands.
2. Site collections of fewer than 50,000—Each site collection should hold no more than 50,000 users for optimal performance.
3. Subsites to a website fewer than 2,000—More than 2,000 subsites of any one site
slows server performance.
4. Documents in a single folder of a document library fewer than 10,000 —
Performance degrades if more than 10,000 documents are stored in a single folder.
Using multiple folders, however, increases this limit to almost two million documents.
5. Items in a view fewer than 2,000—Any more than this slows access.
6. Fewer than 100 web parts per page—Loading more than 100 web parts slows
down the users’ ability to view a page.
7. Individual document size less than 50MB—The bigger a document grows, the
greater strain that document has on an environment. The default “hard limit” in
SharePoint is 50MB; any larger documents would seriously slow down the server.
The maximum document size is 2GB.
