Excel Services capacity planning (SharePoint Server 2010)
Applies to: SharePoint Server 2010
Topic Last Modified: 2011-10-14
Many factors, including Excel Services in Microsoft SharePoint Server 2010, can affect the performance and availability of your Microsoft SharePoint Server 2010 deployment. These include network bandwidth and resource consumption. Excel Services can affect system performance, depending on the volume of client connections and the number of concurrent Excel Calculation Services session requests. Calculation size and complexity can also affect Excel Calculation Services resource consumption.
The scope and complexity of calculations in a Microsoft Excel workbook rendered using Excel Services can affect the performance and availability of Excel Services in a SharePoint Server 2010 deployment. As calculation volume, complexity, and frequency increase, more system resources are consumed. We recommend that you define baseline hardware requirements for system memory and CPU capacity for each application server that runs Excel Calculation Services.
For detailed information about how to estimate performance and capacity requirements for Excel Services, see Estimate performance and capacity requirements for Excel Services in SharePoint Server 2010.
You can now run Microsoft Excel 2010 workbooks and user-defined functions on a Windows HPC cluster by using Windows HPC Server 2008 R2. For information about how to use Windows HPC Server 2008 R2 with Microsoft Excel 2010, see HPC Services for Excel.
