Original link: Benchmarking Java Performance Of JDK 8 Through OpenJDK 27 / Phoronix.
No surprises. Steady small improvements over time.
Note that they have just tested standard Hotspot JVM. There is also IBM J9 JVM and Graal JVM. My experience is that IBM J9 is occasionally faster than Hotspot while Graal is usually slower than Hotspot.
