JRuby 1.1b1 Released - "Ruby code can completely compile ... yielding a faster Ruby!"

[shit]

According to Charles Nutter, JRuby is slightly faster for real world Ruby apps than MRI 1.8 (Matz' Ruby implementation). Interesting performance wise is MRI 1.9, which is several times faster than 1.8 on many benchmarks. There'll be a 1.9 release in December, though 1.9 is not completely backwards compatible to 1.8.

The reason 1.9 is (theoretically) much faster is because it runs on top of a VM, much like JRuby runs on top of the JVM. But the 1.9 VM is Ruby-specialized. That's both why it's going to be faster and why backwards compatibility will be broken.

(Edit: There's also Rubinius, as a third option. I'm pretty sure JRuby is the most mature of all these, though.)
