The speed of Ruby with the memory management of Java, what's not to love?

Also, now you have two problems.

Java has quite possibly the best production GC of all the VMs out there.

And yet operating distributed systems built on it is a world of pain. Elasticsearch, I am looking at you. Modern hardware resources leave the limitations of running/scaling on top JVM to be an expensive, frustrating endeavor.

In addition to elasticsearch's metrics, there's like 4 JVM metrics I have to watch constantly on all my clusters to make sure the JVM and its GC is happy.

For me, it solves a very specific problem.

In-house app that uses jdbc, is easy to develop and needs to be cross-platform (windows, linux, aix, as400). The speed picks up as it runs, usually handling 3000-5000 eps over UDP on decade old hardware.
