[GraalVM @graalvm]

Accelerating the GraalVM release train and announcing new commercial support!🚀🏆

@filpizlo What exactly do you use it for? Do you allow your agents to log into any websites and if so, how? 😅

[Fabio Niephaus @fniephaus]

GraalVM CE can now sandbox untrusted JavaScript and WebAssembly code! 🚀

As AI generates more and more of the code we run, the ability to execute it safely matters more than ever.

We have more coming that builds on this, so stay tuned!

@Sharat_Chander @Oracle Sorry to hear this, Sharat. I've really enjoyed working with you. Wishing you all the best for what’s next.

GraalWasm just got faster! 🔥

The new threaded interpreter delivers significantly better interpreter performance. In interpreter benchmarks, total execution time is reduced by 5-40%!

Excited to speak at #WasmCon Europe next Monday about bringing #WebAssembly to the JVM ecosystem with @GraalVM.

I’ll demo GraalWasm in a Spring Boot app and show how GraalVM can compile JVM apps to Wasm for browser, mobile, and cloud. Join us!

@ARCaputo3 @alina_yurenko @graalvm AWT works in native images on Linux and Windows, but requires additional app-specific reachability metadata, at least currently. The easiest way to get started is to run your tests with the tracing agent to collect this metadata: https://t.co/xFE3uwSod5

[Fabio Niephaus @fniephaus]

@KiyayYippee @alina_yurenko @graalvm Sure, newer versions of Spring MVC come with out-of-the-box support for @GraalVM. Just compile your app with GraalVM and you should be good to go. :)

[Fabio Niephaus @fniephaus]

@vineelyalamarth @alina_yurenko @graalvm She compiled the Spring Boot app with @GraalVM. Here's a guide: https://t.co/ntQIM2l8rn

[Fabio Niephaus @fniephaus]

@brunoborges @starbuxman Would be interesting to include a @GraalVM-compiled version of the Spring app in the comparison. Could get memory usage much closer to Go without sacrificing latency and throughput.

[Аlina Yurenko 🇺🇦 @alina_yurenko]

GraalVM in action: wouldn't it be cool to move your workload from using 43 replicas to 12, and CPU cores from 15 to 5, reducing resources usage by ~67%? You can do so with @GraalVM Native Image!

[Aki 💙💛 @Logico_jp]

.@fniephaus is now talking about GraalWasm at @Jfokus! / GraalVM + Wasm: Fast, Efficient, Portable Apps

[GraalVM @graalvm]

Good morning #JFokus!👋
Make sure to catch @shaunmsmith and @fniephaus to ask anything you want to know about GraalVM & WebAssembly, and attend their session on Wednesday!

[GraalVM @graalvm]

GraalVM 25.0.2 is now available! 🚀

Upgrade to get the latest security updates and improvements.

[Fabio Niephaus @fniephaus]

@thomaswue @parttimen3rd @graalvm Turns out our handling for `--version`, `--help`, and `--help-extra` in the `native-image` launcher was unnecessarily slow, but that was relatively easy to fix: https://t.co/NfYIfMceho

[Fabio Niephaus @fniephaus]

@thomaswue @parttimen3rd @graalvm See for example: https://t.co/VEfZkcX9YJ

[Fabio Niephaus @fniephaus]

GraalVM Native Image is ~3.5x faster than SapMachine… 😉

… in @parttimen3rd's version string benchmark.

Why? The `native-image` launcher is a native image itself. So it starts up much faster, and uses fewer CPU and memory resources!

OpenJDK is faster than GraalVM*: https://t.co/edQAqS30kW

[Fabio Niephaus @fniephaus]

@parttimen3rd @thomaswue @graalvm Makes sense. GraalVM is slightly slower because it not only enables JVMCI, it also uses it to install the Graal compiler.

[Fabio Niephaus @fniephaus]

WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec.

Join @shaunmsmith and me at @Jfokus next month to learn more: https://t.co/8Xrk5mlY7V
