Re: 80-100 per cent faster than what you can do with static compilation
Full disclosure, I work for Azul.
To address the comment, it's not a comparison with C++/Rust compiled code, it's a comparison with statically compiled Java code.
JIT compilation can take advantage of techniques that definitely lead to better performance. More aggressive method in-lining is only possible if you know what classes are loaded at runtime (not possible with AOT). More importantly, is the benefit of speculative optimisations that are not possible in AOT code. PGO helps but it's still not possible to get the most significant improvements in performance this way.
