GC Tuning Confessions of a Performance Engineer

Performance tuning is a methodical and an iterative process. It is imperative to have a performance plan coexist with a product development plan. As a JVM/GC performance engineer, the speaker will walk everyone through a performance issue which was identified by choosing the right performance metric.
