GraalVM is the new kid on the JVM block. It is an open-source Virtual Machine that is able to run many programming languages, such as Java, Rust, and JavaScript, at the same time. GraalVM has also a new internal code optimizer pipeline that can improve performance significantly compared to other JVMs under some conditions. Learn how to reap the benefits of GraalVM and execute your code faster with no code modification.
What Is GraalVM?
Previous JVMs, such as Oracle JVM and OpenJDK JVM (both called "HotSpot"), have been around for a long time. They have evolved considerably over time and, over the course of the decades, we have seen performance rocket compared to Java 1.0 JVM. Significant JVM improvements include just-in-time compiling (JIT), C2 compiler, escape analysis, etc. that all contributed to this positive development. But as with all technology, they will start to plateau at some point.
