Lucee on GraalVM

omarpta · September 10, 2019, 7:35pm

I successfully ran Lucee on a GraalVM Java without no extra effort. Using the Express installation it is booting gracefully and my feel it’s faster then normal java but didn’t benchmark/measured yet.

GraalVM is a universal virtual machine for running applications written in JavaScript, Python, Ruby, R, JVM-based languages like Java, Scala, Groovy, Kotlin, Clojure, and LLVM-based languages such as C and C++.

GraalVM removes the isolation between programming languages and enables interoperability in a shared runtime. It can run either standalone or in the context of OpenJDK, Node.js or Oracle Database.

I’m curious to know if anyone ever did something more than this. It would be nice to know what GraalVM could bring in combination with Lucee in terms of benchmarks.

I think the real benefit of GraalVM is the fact that you can compile to native, which results in Java applications to have super fast startup times and a lot less memory consumption. This would be really interesting if you want to make your CFML code available for the cloud.

However compiling to native will not work with Lucee in combination with either Jetty or Tomcat, is what I understand now.

Of course there is an alternative: Fuseless for AWS Lambda. But that is more a FAAS solution.

Cheers.

Four years later…
Looks like there might be a way to do it with tomcat and Graal , although it takes some tweaking for reflection that I am pretty sure we do a bunch of in Lucee:

https://tomcat.apache.org/tomcat-9.0-doc/graal.html

When I have some time I might dig into this!
