JVM Performance Comparison

Explore a comprehensive comparison of JVM performance in this 55-minute conference talk from Devoxx. Dive into the complexities of JVM tuning and discover the most suitable JVM and JDK version combinations for optimal performance. Learn about the research conducted by Ionuț Baloșin and Florin Blănaru, who created representative performance benchmarks for specific code patterns using various JDK versions and JVM providers. Examine the performance of Just In Time (JIT) Compilers, including C2 JIT HotSpot and Graal JIT, as well as different Garbage Collectors such as SerialGC, ParallelGC, G1GC, ZGC, ShenandoahGC, and EpsilonGC. Gain insights into the strengths and weaknesses of each JVM and identify the most optimal mix of JDK version and JVM distribution for real-world business applications. Understand the benchmarking stack used in the research, including Java Microbenchmark Harness (JMH), HotSpot OpenJDK, GraalVM CE, GraalVM EE, JDK 11, JDK 17, and both aarch64 and x64 architectures.
