Writing a Java Profiler in Pure Java
Profilers help to analyze performance bottlenecks of your application if you know how to use them. Getting to grips with profilers helps to understand how they work: Profilers aren't rocket science. A usable Java profiler can be written in 240 lines of pure Java code, allowing you to fix performance issues and add custom features quickly. This talk will give the fundamentals of Java profiling and an overview of existing open-source profilers.
