Learn techniques for writing performant JVM code and effective use of tools for analyzing performance.

<h2>Overview</h2><p>The JVM is a rock-solid, battle-proven platform for developing and deploying applications. Thousands of engineering years have been invested into the facilities available on it, resulting in sophisticated garbage collection and just-in-time compilation mechanisms. The interaction between this platform and our applications is nuanced and often misunderstood.</p><p>In this 5-day workshop, the participants will learn about the two major runtime mechanisms of the JVM affecting performance - the JIT compiler and the garbage collector; techniques for writing performant JVM code and effective use of tools for analyzing performance.</p><h2>Who Should Attend</h2><p>Engineers, SREs and tech leads responsible for production JVM applications.</p><h2>Prerequisites</h2><p>Basic knowledge of the JVM; basic experience running JVM applications in production.</p><h2>Topics</h2><ul><li>Overview of the JVM</li><li>Garbage collection on the JVM</li><li>Types of garbage collectors and choosing a garbage collector for a workload</li><li>Analyzing allocations in JVM code</li><li>Writing JVM code that is lean on allocations</li><li>Analyzing bytecode to pinpoint allocations</li><li>Monitoring garbage collector performance at runtime</li><li>Understanding JIT compilation on the JVM</li><li>Benchmarking code using JMH</li><li>Analyzing JIT behaviour at runtime</li><li>Writing JIT-friendly JVM code</li><li>Using Yourkit to monitor JVM performance at runtime (and on Kubernetes)</li></ul><h2>Daily Structure</h2><p>5 days, 4 hours a day starting at 07:00 am London Time, until 11:00 am London Time.</p><h2>Attendance</h2><p>Attendance at this workshop is fully remote. Attendees will be provided with a link to a remote meeting session the day before the event, in which they can see and hear the workshop, ask the instructor questions, and chat with other attendees. </p><h2>About the Author</h2><p>A mathematician by training but a software engineer by vocation, John A. De Goes has been professionally writing software for more than 25 years. John has contributed to dozens of open-source projects written in functional programming languages, including ZIO, a library for asynchronous and concurrent programming in functional Scala. In addition to speaking at Strata, OSCON, BigData TechCon, NEScala, ScalaWorld, Scala IO, flatMap, Scalar Conf, LambdaConf, and many other conferences, John also published a variety of books on programming. Currently, John heads <a href="https://ziverge.com/" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Ziverge Inc</a>, a company committed to solving hard business problems using the power of functional programming.</p>
