Performance tuning is a methodical and an iterative process. It is imperative to have a performance plan coexist with a product development plan. A performance plan not only serves to document the requirements but also feeds into designing the performance experiments and helps in providing a clear understanding of the performance infrastructural needs. During this session, the speaker will briefly discuss performance metrics, tuning tradeoffs and goals and will also talk about her experience with three garbage collectors in OpenJDK's HotSpot JVM - Parallel Old, CMS and G1 and compare and contrast them.
