That's not the graal backend. The TruffleRuby project uses Graal to make JRuby much, much faster. I don't know what the specific information, but generally "competitive with Java" is my understanding. Perhaps "TruffleRuby" is the name I should have used; it's not apparent and I'm only nominally familiar with the project.

Current Status: "TruffleRuby is progressing fast but is currently probably not ready for you to try running your full Ruby application on."

Ok, I was wrong about Ruby, but my point stands--Python and PHP are not even "speed demons" of the so-called scripting languages.
