Explore enterprise JVM performance tuning techniques in this 55-minute conference talk from GOTO Aarhus 2012. Dive into real-world scenarios addressing memory usage, object creation, I/O throttling, serialization, benchmarking, and testing. Learn how small changes can significantly impact JVM application performance, when to prioritize optimization over object-oriented elegance, and the true impact of object allocation on modern JVMs. Gain insights into developer misconceptions about bottlenecks and discover practical approaches to JVM tuning. The presentation covers topics such as working with byte arrays instead of strings, managing memory efficiently, avoiding over-engineering, and understanding JVM memory allocation. Includes demonstrations of useful tools for performance optimization and real-world examples from the speaker's experience as CTO and founder of Incept5.
