Why is Java 24 claimed to be faster than previous versions?

Java 24 is faster due to multiple performance enhancements across various OpenJDK projects. Oracle and other organizations are investing significant efforts in JIT compiler improvements to optimize code execution. Projects like Loom (virtual threads), Panama (native function calls and vector support), and Valhalla (object flattening) contribute to performance gains. Additionally, memory optimization initiatives such as Lilliput (shrinking object headers) improve memory efficiency and code locality, while ZGC improvements and Leyden project focus on startup and warm-up time optimization, particularly beneficial for cloud deployments.
