A Journey to JVM Excellence - Navigating JDKs and JVMs

Explore a comprehensive analysis of JVM performance optimization in this 48-minute conference talk from Devoxx. Dive into the challenges of JVM tuning and discover the research findings of Ionuț Baloșin and Florin Blănaru on identifying the most suitable JVM and JDK version combinations. Learn about their benchmarking approach using specific code patterns, focusing on Just In Time (JIT) Compilers like C2 JIT HotSpot and Graal JIT. Gain insights into the strengths and weaknesses of different JVMs and understand how to select the optimal mix of JDK version and JVM distribution for improved performance in real business applications. The talk covers benchmarks using Java Microbenchmark Harness (JMH), HotSpot OpenJDK, GraalVM CE, Oracle GraalVM, JDK 17, and both aarch64 and x64 architectures.
