Java (and CPU) Performance Puzzles
Our modern JVMs and CPUs are capable of some amazing feats of optimization. In general, for day-to-day work, these optimizations just work, but they also mean that the optimal approach can be surprisingly unintuitive.
In this presentation, we'll examine some surprising performance anomalies. Through learning the mechanisms behind these performance paradoxes, you'll gain insight into how modern compilers and hardware work.
