Sun Java System Web Server 6.1 SP7 Performance Tuning, Sizing, and Scaling Guide


On Solaris and Windows, Sun Java System Web Server transparently takes advantage of multiple CPUs. In general, the effectiveness of multiple CPUs varies with the operating system and the workload. Dynamic content performance improves as more processors are added to the system. Because static content involves mostly IO, and more primary memory means more caching of the content (assuming the server is tuned to take advantage of the memory) more time is spent in IO rather than any busy CPU activity.
