As web architectures evolve over time, they tend to spawn components which rely on JVM technologies. How can operations teams & developers who aren’t Java/JVM specialists solve performance problems & understand the behaviour of these components?

In this session, Ben Evans will provide a HItchhiker’s Guide to JVM performance – how to measure it, how to diagnose it, & how to avoid the pitfalls of “performance tuning by StackOverflow”.

The hands-on element deals with the performance tuning of an example badly-performing OSS app, and applies the theory to provide an empirical method for analysing JVM components in real production environments.
