True! I just checked again and Topaz is indeed almost twice as fast as CRuby on optcarrot. I think I got it mixed up with the non-JIT Rubinius numbers.

It'a shame Topaz was never really "finished".

One of the main Topaz developers now works on the Python equivalent of TruffleRuby.

You mean a python implementation on truffle? Or ruby on something truffle-like on RPython?

[chrisseaton]

The former.

This is the answer I wanted :-)
