Application Tier Performance

Policy Servers evaluate polices in the application tier and user credentials and attributes in the data tier to protect resources. Consider the following guidelines to performance tune the application tier:

• The amount of system resources required to authenticate users affects performance.
• The amount of system resources required to authorize users affects performance.
• The number of Policy Server requests to SiteMinder user directories during authentication and authorization affects performance.
