I understand that most of the performance boost comes from the the invokedynamic optimization, not from anything special inside JRuby.

So, does this mean we can expect the same goodness for other dynamic JVM languages? Clojure maybe?

there is the need for the implementation to actually make use of invokedynamic, otherwise there would be no gains. As for clojure: http://news.ycombinator.com/item?id=2928285
