I remember longer stop-the-world GC pauses in our simple GC implementation, and leakage issues related to JS interop. I didn't work on that back then, can check with the team for details.

Our GC implementation for linear memory wasn't very sophisticated, but we also wanted to avoid overhead in JS interop and reduce overall file size.

GraalVM targets Wasm GC.
We started with linear memory but GC performance was simply not good enough.

Fabio @fniephaus.com will introduce Web Image, a new preview feature of GraalVM that enables compiling applications into efficient Wasm modules, including use cases and live demos.
We'll also look at GraalWasm, a new embeddable Wasm runtime.

In Oracle JDK, the Graal JIT has only ever been an experimental feature. Most people using Graal JIT do so via a GraalVM distribution where it’s enabled by default, so nothing changes for them. 🙂

My favorite is probably the DAP and Chrome Inspector debugging support in #GraalWasm, based on DWARF. 🤓

Hi @joschi.xyz,
we have information available in the GraalVM Download Service (GDS), but it's unfortunately not publicly documented and the format is missing download links.

Example: gds.oracle.com/api/20220101...

I hope we can soon provide something closer to Disco and Java Release Metadata.

Time, and/or @hansolo.eu 😅

I checked with the team, and we do run the PolyBench/C benchmarks on GraalWasm. Performance is comparable to Node.js—typically between 1x and 1.5x (never better, but also never worse than 2.25x). We are, of course, actively working on improving this. 🙂

The preview of the JavaScript interoperability API for GraalVM Web Image is now available on Maven Central: central.sonatype.com/artifact/org...

This release also includes various fixes, though support for the component model, threading, and more still needs work. Contributions are welcome! 🙂

I don't see any 25 release on @sdkman.io yet, but GraalVM should become available in a few hours. 🤞

Thanks, we'll take a look!

Not yet. We've been benchmarking against use cases we find interesting, but I'm not sure how representative they are.

What numbers would you be interested in? Can you recommend a benchmark suite for WebAssembly runtimes?

Don't worry, we are not going anywhere and we will continue our mission to run programs faster and more efficient. 🙂
