Abstract Have you heard about the latest garbage collectors (GCs) in OpenJDK HotSpot VM? Are you interested in learning more about their algorithm and design goals? Would you like a basic comparison between them and the current default collector in OpenJDK? If you answered yes to any of the above questions, then this is the … Read More
As a JVM/GC performance engineer – I always ask pertinent questions such as – what are performance expectations of the product by the stakeholders? what are the important metrics?, what are the tuning goals?, etc. and then I discuss tradeoffs and finally establish tuning goals.
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.
On the show today, Java Performance tuning expert Monica Beckwith. Monica worked at Sun and Oracle as a performance engineer, and contributed a lot of optimizations and tuning advice to the JDK Hotspot team. She is an Performance Tuning consultant today, working on advising clients on how to best balance aspects such as throughput, latency, … Read More
