(Update: After some head scratching I finally got to an irb prompt and have written up instructions on that post on getting it all running on OS X. The announcement post doesn't really go into anything and I couldn't find a README.)
(Update 2: I ran a VERY flimsy benchmark from the Alioth shootout - the Fannkuch benchmark - on 1.8.7, 1.9.1, MacRuby and MagLev and get these results:
1.8.7 - 6.276s
1.9.1 - 3.539s
MagLev Alpha - 2.975s
MacRuby 0.5b2 - 4.649s
MacRuby 0.5b2 (compiled) - 2.901s
JRuby 1.4.0 (basic) - 5.579s
Take with a pinch of salt, etc. It's a single benchmark under less than scientific conditions.. I bet half of that JRuby figure, for example, is JRuby starting up the JVM ;-))
Not exactly sure of the license, but they do have something on GitHub. I believe Maglev itself is open source, but it relies on the GemStone/S VM, which is NOT open source.
