This is SPECjvm2008 modified to run with JDK24. Scores are ops/min, more is better. All benchmarks have been run on a AWS c5.9xlarge instance.
JVM flags: -Xms8g -Xms8g Xmx8g -XX:+AlwaysPreTouch
Notes: The CryptoRsa benchmark shows a legit regression of ~2%. I confirmed this by running 50 times (most benchmarks are run 3 times). The regression disappears when improving oopDesc::klass().
