We've really only scratched the surface of optimizing JRuby's core for
frameworks like Rails, and I suspect a lot more will come in the
future. We didn't consistently run Rails faster than MRI until the 1.2
release a few months ago, so the fact that we post consistently better
numbers now is very promising.
If you have any specific areas that appear to be slower under JRuby,
we would very much like to hear about them. But it sounds like you've
managed to get the solid performance you were hoping for, and we'll
continue to improve in the future :)
One thing that's useful to note about JRuby versus Ruby 1.9: There's
no way to run a single instance of Ruby 1.9 for an entire multi-core
box, since it does not yet run threads concurrently. So that's one
advantage we have (above and beyond the JVM and Java ecosystem).
