Native Image is an *amazing* technology!

Having a 150mb+ JAR full of weird compiler stuff (from jrtfs to Swing!) in kotlinc quite easily built with Native Image, and immediately yielding this kind of improvement is outstanding.

Looking forward to what's next 👀
The @kotlinlang.org team at @jetbrains.com is working on a @graalvm.org-compiled kotlinc. Early experiments look very promising:

> So far, a native image with PGO offers a properly "warmed-up" kotlinc and with up to 20% more peak throughput.

First Day: A New Chapter at the JKU

It's Wednesday. Is this important? It's my first day in a new position. So, perhaps the real question is: what's going to be important to me from now on?

This project will build on the existing GC infrastructure in Native Image, with initial support for Linux/amd64 and Linux/aarch64, and potentially more platforms in the future.

We are excited about this contribution and the benefits it will bring to the GraalVM community!

Running native extensions in parallel is a huge performance boost. Running a large internal Rails application, we saw performance roughly double. Very workload dependent, of course, but all of the major DB adapters are implemented as native extensions.

We also added support for the blake3-rb gem.
