native-image -O3 -o myapp myapp.jar ./myapp …and it’s up before my terminal finishes rendering.

Then GraalVM walked into the room.

The Graal Upload Era: When Native Java Stopped Being a Punchline

If you haven’t tried spring-native or quarkus in native mode in 2024/2025, do yourself a favor. The future of the JVM is . graal upload era

We went from: “Java for microservices? LOL, cold start goes brrrr.” To: “Yeah, our entire trading edge service is a native Java binary. It runs on a Raspberry Pi.

For the past 20 years, the "write once, run anywhere" promise had a dirty secret: it only ran well after a long, painful warm-up. Cold starts were the enemy. Serverless was a fantasy. And native images? That was for C++ folks.
