Will Graalvm Replace Hotspot?

The GraalVM Compiler is a modern Java just-in-time compiler. It complements or replaces the existing compilers (C1/C2 in HotSpot). In contrast to those existing compilers, the GraalVM compiler is written in modular, maintainable and extendable fashion in Java itself.

Does GraalVM use HotSpot?

GraalVM is based on Java HotSpot VM, but integrates an advanced just-in-time (JIT) compiler, written in Java - the GraalVM compiler. At runtime, the application is loaded and executed normally on the JVM.

Is GraalVM faster than HotSpot?

It turned out that GraalVM is a bit faster overall than HotSpot but there are some outliers to the left, i.e. some problems where we can observe a severe performance degradation. The native image, however, is 50% slower on average (in terms of moves per second) than HotSpot.
