How to Configure Policy Servers Under Heavy Loads

If the load requirements of the Policy Server serving your site are large (any number that requires a great deal of CPU usage), you can:

Turn Off Logging—Unless you are tracking log information for a specific reason, such as troubleshooting or monitoring usage, turn off logging. Logging may have an adverse affect on performance.
Add Memory—Add more memory to the servers hosting the Policy Server. This will enable you to set a higher number of maximum sockets for the Policy Server.
Add Additional Policy Servers—Adding additional Web servers for more Policy Servers enables the site to support more users and resources. Each Policy Server can be configured to use the same policy store. The Web Agents in the site can then be configured to use different Policy Servers, which spreads the load requirements among the multiple Policy Servers and improves performance.
