Purpose

This article provides information that helps you to understand the challenges and processes associated with performance tuning in Tomcat.

Resolution

Tomcat performance includes these factors:

• Responsiveness – Servicing individual requests with minimum delay. Requests may even have a Service Level Agreement (SLA) to meet.
• Throughput and scale – Maximizing the overall traffic or load that Tomcat can handle over time.
• Stability and security – Ensuring that Tomcat functions correctly under heavy traffic, unusual load, or even attacks.

This article provides links to some of the guidelines that are offered in  SpringSource Webinars and  TomcatExpert.

Impact/Risks

All settings represent a trade-off between different approaches intended for different situations. During performance tuning, you should always load test and profile your specific application(s). It is important to be able to measure the specific performance gains (or losses) from making any adjustments to the settings.  If you cannot do that accurately, it is impossible to determine how to maximize performance.
