> I always wondered how much power could be saved if those platforms would be implemented nearer to the metal. > JPHP where PHP could run on top of the JVM, since that introduces way more languages like Scala, Groovy, Java itself Using the JVM to move closer to the metal only works if you use another statically typed language with it, so only Scala and Java would qualify in this regard. Groovy's a dynamically typed language used for scripting and hence fairly slow. The static typing they introduced in version 2 didn't have any uptake, either on the JVM in version 2.0 or on Android in version 2.3, hence it's still buggy for this use case.
