Erlang vs. Java benchmarking update

As an update to my last post, I didn’t find an image which goes to 100.000 tasks for performance, but the Kilim guys have a graph for creating 200.000 tasks.

Perhaps they implement an supervisor architecture too. And perhaps this makes it into a future JDK.

Update: There is also a Google talks video about Kilim on YouTube.

It is a good sign that Erlang’s core concepts are pushing their way into the Java community. This may be just the thing to carry Java across the paradigm shift that multi-core is forcing in programming. Given the immensely larger development resources devoted to JVM performance I am surprised that the gap is not larger in Killim’s favor.

Killim is a very interesting initiative and one which I will be watching closely.

Yes. And one of the strengths of Java is to evolve and incorporate other ideas.

Cannot find the sources of Java and Erlang ones.

And actually very very funny results. According current graph previous one was incorrect :) And for 3000 tasks Erlang is faster :)

So, were these tests made in Photoshop?

The article is 2 years old, Kilim might no longer be the actor framework of choice.

The graph can be found in one of the presentations, the source should be easy, plain message passing.

There is a newer comparison paper for actor frameworks in Java:
