This is pretty exciting, I tried it out in the docker tech preview and it was pretty quick, especially once the JIT kicked in. I'm going to try to build it locally and se how it works outside of the prepared environment.
Yeah, I tried it as well and it shows some promise. Its good to see IBM throwing some resources at making Ruby faster.
Mark Stoodlet's VM talk from last year is really good. And Gracie's talk on Ruby from February was pretty cool as well. I wonder if they are in touch with koh1 and the other people working on 3x3.
