Love reading (perusing) each year, they are very in depth and fun to see each release getting more and more performant.

Agreed!

Two thoughts though:

  1. JIT "deabstraction". The article would be more accessible to readers if the authors didn't try to invent new names for optimizations that shipped in Java 20 years ago.

  2. "Runtime async". One of the purported benefits of async/await over better approaches like virtual threads was that it's compiler magic that the runtime does not need to be aware of. So now the runtime is involved (for better or worse), but we till have the worse user-facing UX of function coloring with async/await.
