Sharepoint : ResourcePoints for Sandbox solutions

To restrict the resources that your sandboxed solutions consume, you define resource points. Resource points correspond to specific levels of resource usage that you can define for up to 15 system resources that you want to monitor. Each of these resource measures accumulates points based on a single sandboxed solution's use of that resource, and those points are aggregated toward a quota that has been set for the whole site collection. If the number of accrued resource points exceeds the quota set for the site collection, all sandboxed solutions in the site collection are stopped. For a list of the individual resource measures and the minimum threshold, absolute limit, and resources per point for each resource, see Resource Usage Limits on Sandboxed Solutions in SharePoint 2010 (http://go.microsoft.com/fwlink/p/?LinkId=217149).

Quotas are managed through the SharePoint Central Administration Web site as a single number that controls the aggregate total of the resource points allowed per day for all sandboxed solutions in a site collection. For more information about quotas, see Sandboxed solutions overview (SharePoint Server 2010). For information about how to set the maximum resource quota for a site collection, see Change the storage limits for a site collection in Manage site collection storage limits (SharePoint Server 2010).

You can fine-tune the resource point distribution by using Windows PowerShell, as described in this article. When these Windows PowerShell commands are added to a script, you can configure the individual resource point distribution within the sandboxed solution quota for a site collection. For more information about quotas and resource points, see Sandboxed solutions overview (SharePoint Server 2010).
