<\/span>Get maximum performance from Apache Tomcat<\/span><\/h2>\n

A question we often get asked by customers is: what Tomcat performance tuning<\/a> can they do to improve the overall performance. This guide is everything we know about tuning Apache Tomcat for maximum performance.
\n\"Tuning<\/p>\n

Apache Tomcat<\/a>, developed by the Apache Software Foundation, is an open source Java servlet container that also functions as a web server. While over 100,000 websites rely on Tomcat as a web server, a Plumbr survey of Java application servers showed that over 60% of websites that use Java technology relied on Apache Tomcat to host the business logic.<\/p>\n

Production environments must be high performing. This requires that Apache Tomcat be configured to handle the maximum load possible and yet provide the best response time to users. The performance that an application server delivers is often dependent on how well it is configured. Often the default settings provided are non-optimal.<\/p>\n

At eG Innovations, our eG Enterprise IT performance monitoring solution<\/a> uses Apache Tomcat as the web server. Over the years, we have discovered several tips and tricks for configuring Tomcat to achieve the highest level of scalability possible. This blog post documents our learnings on best practices that you should employ when deploying Tomcat in production.<\/p>\n

<\/span>A holistic approach is needed for tuning Tomcat performance<\/span><\/h2>\n

A first step to achieving high performance is to recognize that tuning the Tomcat application server alone is not sufficient. After all, Tomcat runs on top of a Java virtual machine<\/a> (JVM). So, a poorly configured JVM will compromise performance. Likewise, the JVM runs on an operating system and it is important to have the best possible operating system configuration to achieve the highest performance possible. Even bottlenecks in the application code<\/a> can result in “Tomcat is slow” complaints. All in all, a holistic approach must be taken for Tomcat performance tuning.<\/p>\n

Performance tuning must be done at every layer: the operating system, JVM, Tomcat container, and at the application code level<\/div>\n

In the following sections, we will present best practices to configure the operating system, JVM, Tomcat container, and application code for best possible performance.<\/p>\n
