What problems is GraalVM solving and how is that benefiting you?

GraalVM has the ability to compile Java applications ahead of time into a native binary. This will result in instant startup of the application and consuming significantly less memory compared to traditional JIT (Just in Time) compilation setup. Though JIT is preferable for optimizing for peak performance, but for startup and memory footprints the native images can offer very competitive advantages. GraalVM is a high-performance virtual machine, showcasing enhanced performance optimizations for individual languages and smooth interoperability for polyglot applications.
