That's awesome - so it'll have a JVM of sorts bundled within it but that's totally hidden, it runs just like MRI? How does memory usage compare - running JRuby

That's awesome - so it'll have a JVM of sorts bundled within it but that's totally hidden, it runs just like MRI? How does memory usage compare - running JRuby on a 512mb dyno would be sweet. What you + the jruby team is doing is truly awesome, at some point I'll have to try my hand at contributing to it :)

Yeah, but it's not just bundled - to me that it sounds like we just link against a JVM library to produce a binary. What we do is to compile the Ruby interpreter, the JIT compiler and the JVM runtime in one big step - whole program analysis. Memory usage and startup time are comparable to MRI - http://www.oracle.com/technetwork/java/jvmls2013wimmer-2014084.pdf http://www.oracle.com/technetwork/java/jvmls2013wimmer-20140... see slide 19.
