Sun Java System Web Proxy Server 4.0.11 Performance Tuning, Sizing, and Scaling Guide

Low-Memory Situations

If Proxy Server must run in low-memory situations, reduce the thread limit to a bare minimum by lowering the value of the "Request Throttle" at "Configure System Preferences" in the Admin console.

The server automatically selects many server defaults based on the system resources, for optimal performance. However, if the server's chosen defaults are not suited to your configuration, you can override them. .

The File Cache configuration, especially when non-default, can impact memory usage. Similarly, the ACL Cache size should be controlled using the ACL Cache Tuning in Sun Java System Web Proxy Server 4.0.11 Release Notes, if needed.
