Article contains information to help you understand the tested performance and capacity limits of SharePoint Server 2010, and offers guidelines for how limits relate to acceptable performance. The test results and guidelines provided in article apply to a single SharePoint Server 2010 farm. Adding servers to the installation might not increase the capacity limits of the objects that are listed
- Boundaries, thresholds and supported limits
In SharePoint Server 2010, there are certain limits that are by design and cannot be exceeded, and other limits that are set to default values that may be changed by the farm administrator. There are also certain limits that are not represented by a configurable value, such as the number of site collections per Web application. - How limits are established
- The Equalizer Metaphor
- Limits by hierarchy
- Web application limits
300 Content databases per Web application
5 Zones per Web application
20 Managed paths per Web application - Web server and application server limits
10 Application pools per Web server - Content database limits
200 GB per content database
Content database sizes up to 1 terabyte are supported only for large, single-site repositories and archives with non-collaborative I/O and usage patterns, such as Records Centers.
When SharePoint Server 2010 is configured to use RBS, and the BLOBs reside on NAS storage, consider the following boundary. From the time that SharePoint Server 2010 requests a BLOB, until it receives the first byte from the NAS, no more than 20 milliseconds can pass

A site collection should not exceed 100 GB unless it is the only site collection in the database. - List and library limits
