Graal: How to use the new JVM JIT compiler in real life by Chris Thalinger

HN Theater has aggregated all Hacker News stories and comments that mention Devoxx's video "Graal: How to use the new JVM JIT compiler in real life by Chris Thalinger".
Youtube Summary
With JEP 317: Experimental Java-Based JIT Compiler it is very likely that Graal will be part of JDK 10. In fact, Graal is already available in JDK 9 due to JEP 243: Java-Level JVM Compiler Interface. Graal is itself written in Java and that brings some new properties and behavior to the table which we haven’t seen with existing HotSpot JIT compilers. This talk will show how to use Graal with JDK 9, how to compile an upstream Graal version and what to look out for when using it for benchmarking or even in production.

You don't need to run Java services.

Running gitbucket is simply "Java -jar gitbucket.jar"

JVM performance is pretty much world-class (and has been for many years). Golang and JVM compete neck to neck at top of the performance charts. Remember that startup performance is not what Java optimised for - it's long running processes like any web server or api.

And I'm far more excited by Graal than any programming language breakthrough over the past few years ( https://youtu.be/_7yIUkP5LiQ)

Ok, let me rephrase that, if you like to run the JVM do it :)
Here is a more recent one.

From Twitter engineer Chris Thalinger's videos[0] it seems like they're using JDK 9 or 10 and graal via JVMCI. Is there more to GraalVM than just using graal with a particular JDK release?

Yeah there's a whole world of different ways you can use Graal.

They're choosing to use the JIT from CE Graal (which they've built themselves), via the released version of JVMCI in a released JDK.
