• Azul Zulu OpenJDK 15 on Raspberry Pi

    With Azul Zulu OpenJDK 15, for this post I did some experiments with Java 15, reusing the Ubuntu 64bit SD card which was also used for my earlier post “Startup Speed of Spring and Quarkus JARs on the Raspberry Pi”.

    Do you need to switch from OpenJDK 11 to 15? No, not really, based on these results. But each new version has bug and security fixes, new features, and generic improvements!

  • Startup Speed of Spring and Quarkus JARs on the Raspberry Pi

    For my book “Getting Started with Java on Raspberry Pi”, an example was described to store sensors and measurements in an H2-database through REST APIs with a Spring application on the Raspberry Pi.

    The application takes some time to start on a Raspberry Pi, and Adam Bien who does the airhacks.fm podcast, asked me if I could compare this to a similar Quarkus application, which resulted in some nice results.
