Technical Overview of ZingJDK: ReadyNow, Falcon JIT, and C4 GC

ZingJDK, Azul’s high‑performance commercial JDK built on OpenJDK, combines ReadyNow® pre‑warming, the LLVM‑based Falcon JIT compiler, the pause‑free C4 concurrent compacting garbage collector, and a cloud‑native off‑load compiler to deliver dramatically faster startup and execution across JDK 7‑21, though it lacks dynamic Attach support and requires a commercial license.
