Performance Tuning Roadmap

Performance tuning is an iterative process, and as such, it is important to address the Web, Application, and Data tiers on an individual basis to understand how each can affect overall performance. You can often achieve better performance by changing configuration settings in SiteMinder Agents, Policy Servers, or the SiteMinder policy objects themselves. The following diagram represents a standard deployment and details the individual components that are central to performance.

1. The types of Web servers deployed in your environment can affect how a SiteMinder Web Agent and Policy Server communicate. For more information, see Web Server Performance.
2. The number of available sockets can affect the efficiency in which a Web Agent and Policy Server communicate. For more information, see Web Tier Socket Usage and Reduce Traffic between your Web Agent and the Policy Server.
3. SiteMinder policy design can affect the efficiency in which the Policy Server services authentication and authorization requests. For more information, see SiteMinder Policy Design and Performance.
4. The Policy Server performs a series of services to authenticate and authorize users. These services result in number of reads and writes, collectively known as requests, to a user directory. A contributing factor to SiteMinder performance is determining whether your user directories can handle this workload during sustained and peak periods of operation. For more information, see User Store Capacity Planning.
5. The user directory itself can affect SiteMinder performance. For more information, see Data Tier Guidelines.
