Java Performance Update
summary
Roadmap and concrete wins: Project Leyden targets large reductions in startup and warmup by persisting profiling and compiled code into an AOT cache so many apps start “fast from zero”; string toString shows ~2x improvement in examples; stable deferred immutability via stable values lets the JVM constant-fold lazy-initialized fields with record‑level safety (JEP draft sent for review), and surprisingly some FFM bulk ops run faster in Java than intrinsics with a 64‑byte threshold and long indices for huge memory segments.
