Project mention: Is it worth looking at GraalVM native image? | reddit.com/r/java | 2021-12-27

GraalVM native is definitively worth looking at. Still not mature, but getting better. I did small demo project over holidays, and will keep testing this through 2022 with spring and plain java as well. Gains on ARM64 (arm64v8) platforms (raspberry pi 4) are quite visible. If you try this, compilation is slow and takes a LOT of memory. To compile for ARM64, I had to create Quemu VM with 20G of RAM on my x86_64 desktop to create a native image for raspberry pi 4. https://github.com/jveverka/spring-examples/tree/java-17/spring-native
