Others have already posted nice lists of interesting languages, so I will not repeat them. However, for quite few years I have been interrogating google about this subject (in a somewhat lazy-compulsive-obsessive manner). I have never made anything practical because I lacked the time for this. I was just probing a little. So, from what I have read, one can expect a performance drop compared to the same code written in pure Java. Statements like this were repeated in every language's docs I examined. But it seems that things are changing: when compared Scala and JRuby to Java 6 -server, Scala is almost on par with Java while JRuby lags behind. http://shootout.alioth.debian.org/ Of course, benchmarks do not tell the whole truth but they can give some hints. Some JVM-based languages improve faster than others. It could be interesting to run those tests on the mainframe and see what differences there are, if any.
