Sharepoint 2007 Limitations

Site object Guidelines for acceptable performance performance degrades if the below specified limitations exceed.

1. Site collection: 50,000 per Web application Total farm throughput degrades as the number of site collections increases.

2. Web site: 250,000 per 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 100,000 Web sites. The maximum recommended number of sites and subsites is 125 sites with 2,000 subsites each, for a total of 250,000 sites.

3. Subsite: 2,000 per Web site The interface for enumerating subsites of a given Web site does not perform well as the number of subsites surpasses 2,000.

4. Document: 5 million per library You can create very large document libraries by nesting folders, using standard views and site hierarchy. This value may vary depending on how documents and folders are organized, and by the type and size of documents stored.

5. Item: 2,000 per view Testing indicates a reduction in performance beyond two thousand items. Using indexing on a flat folder view can improve performance.

6. Document file size 50MB (2GB max*): File save performance is proportional to the size of the file. 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.

7. List: 2,000 per Web site Testing indicates a reduction in list view performance beyond two thousand entries.

8. Field type: 256 per list This is not a hard limit, but you might experience list view performance degradation as the number of field types in a list increases.

9. Column: 2,000 per document library 4,096 per list This is not a hard limit, but you might experience library and list view performance degradation as the number of columns in a document library or list increases.

10. Web Part: 50 per page This figure is an estimate based on simple Web Parts. The complexity of the Web Parts dictates how many Web Parts can be used on a page before performance is affected.
