10. High-performance JDK distribution
    Increases application throughput, reduces
    latency, reduces memory use
    Graal just-in-time (JIT) compiler that runs on top
    of HotSpot, written in Java
    native-image ahead-of-time (AoT) compiler
    compiles Java applications into small self-
    contained native binaries

11. Micronaut + GraalVM Native Image are a match
    made in heaven
    Less work to configure Native Image because
    Micronaut eliminates reflection, runtime
    proxies, bytecode generation and dynamic
    classloading
    Startup time 20ms and Memory Consumption
    18MB!
