Tuning Microsoft Windows for Enhanced Siebel Server Performance

This topic describes how you can configure settings for your Microsoft Windows operating system to optimize the performance of Siebel Business Applications.

Maximizing Data Throughput

For a server computer on which you install Siebel Enterprise Server software, changing the data throughput setting from Maximize data throughput for file sharing (default) to Maximize data throughput for network applications can result in the following benefits:

• Better Symmetrical Multi-Processing (SMP) scalability
• Improved networking performance
• Allocation of more physical memory for your Siebel applications

NOTE:  Where the Siebel Database is on a server computer running MS SQL Server, the setting Maximize data throughput for network applications is set by default, and is also generally recommended for optimal performance. Whether to keep or change this default depends on how you are using the server computer.

For more information on these settings, see Microsoft's documentation.

Turning on the 4GT RAM Tuning Feature

You can expand the per-process address limit from 2 GB to 3 GB. This reduces the amount of physical RAM available to the operating system from 2 GB to 1 GB. The difference (1 GB) is allocated to your applications. This feature is referred to as 4GT RAM tuning. For information on how to configure this setting, see Microsoft's documentation.

NOTE:  Each Siebel process (Siebel Application Object Manager) cannot use more than 2 GB of RAM.
