Recycling application pools
This task applies only to computers running Internet Information Services (IIS) 7 or above with Windows Server 2003 or 2008.
You should recycle processes periodically, for both stability and performance reasons. Over long periods of time, leaked resources and system or application problems might affect Web server throughput. Balance this with recycling too often, however, since the cost of stopping the worker process, reloading pages and re-obtaining resources and data might override the benefits of a recycle.
▪If there is high load on the interviewing server, you might need to recycle the application pool once a day.
▪If there is low load, you can recycle the application pool once a week, or disable it completely.
By default application pool recycling is disabled for the application pool.
To set up recycling for the application pool
1 Open Internet Information Services Manager.
2 Expand the display in the left pane so that you can see the SPSSmrInterviewPool application pool in the Application Pools branch.
3 Right‑click SPSSmrInterviewPool, and then click Properties.
The SPSSmrInterviewPool AppPool dialog box opens.
4 On the Recycling tab, select the type of recycling you want, and then enter the additional information required.
