Groovy performance is pretty poor in general and is mostly used for writing build scripts. It's a scripting language whereas Scala and Kotlin are better suited to writing large systems. Groovy seems to have stagnated outside of its use with gradle, whereas Scala continues to grow.

I'm curious...why do you say it has stagnated? Seems to still be pretty popular...especially in the gradle and grails spaces. I've done quite a bit of groovy and have really enjoyed it. After years of doing java, and then years of ruby, and then trying to go back to java, I really struggled with rationalizing the move to myself given the immense amount of extra work java required to do anything productive. Groovy made the jump palatable, and in many ways I prefer groovy to ruby. That said, I haven't written any code which is particularly performance sensitive yet. However, groovy now has @CompileStatic, so you can statically compile the perf sensitive bits. I'm sure that doesn't completely solve the problem, but it's an option. I really do hope Kotlin succeeds thought. Having something in the middle of groovy and scala syntax-wise with no performance concerns and the great java integration groovy brings would be spectacular.

  > the great java integration groovy brings I recently wrote some scripts using Clojure to test some Java I'd written. It worked great, and I could use a macro to get rid of some duplication that functions couldn't.

> Groovy seems to have stagnated outside of its use with gradle I don't think Gradle will be using Groovy for too much longer. I looked at the source code for the recently released Gradle 2.0 and they'd replaced almost every Groovy source file with a Java version - only Groovy files specifically related to the DSL were left. And I suspect Gradle will soon open up its configuration as an API any language can use.
