Total throughput degrades as the number of site collections increases.
Web sites
Web site
2,000
The interface for enumerating subsites of a given Web site does not perform well much beyond 2,000 subsites.
Web sites
Site collection

You can create a very large total number of Web sites by nesting the subsites. For example, 100 sites each with 1000 subsites is 100,100 Web sites.
Documents
Folder
2,000
The interfaces for enumerating documents in a folder do not perform well beyond a thousand entries.
Documents
Library
2 million
You can create very large document libraries by nesting folders.
Security principals
Web site
2,000
The size of the access control list is limited to a few thousand security principals, in other words users and groups in the Web site.
Users
Web site
2 million
You can add millions of people to your Web site by using Microsoft Windows security groups to manage security instead of using individual users.
Items
List
2,000
The interface for enumerating list items does not perform well beyond a few thousand items.
Web Parts
Page
100
Pages with more than 100 Web Parts are slow to render.
Web Part personalization

10,000
Pages with more than a few thousand user personalizations are slow to render.
Lists
Web site
2,000
The interface for enumerating lists and libraries in a Web site does not perform well beyond a few thousand entries.
Document size
File
50 MB
The file save performance degrades as the file size grows. The default maximum is 50 MB. This maximum is enforced by the system, but you can change it to any value up to 2 GB (2047 MB) if you have applied Windows SharePoint Services Service Pack 1. For more information, see "Configuring large file support" in Installing and Using Service Packs for Windows SharePoint Services 2.0.
