The standard Ruby runtime isn’t the only one available. JRuby runs on top of the Java runtime, and IronRuby runs on top of the .NET runtime. Rubinius, a virtual machine built specifically for ruby, is also making progress but isn’t yet complete.
Anyone here tried any of these alternatives out yet?
I haven’t used any of them yet, but I’m keeping my eye on JRuby in particular.
Check out this Ruby Implementations Shootout
Yes, I have used JRuby and am quite impressed.
I took a look at all of the different implementations and posted my own shootout
JRuby is looking really promising!
I agree that JRuby is impressive (with obviously the extra bonus of being able to use Java libraries write away) and I also like MacRuby in terms of speed. For a beta release (0.2) it’s speed is really ok and also it can be useful for Mac addicts / programmers :)
If anyone is interested I have posted (some months ago – I should update them at some point!) some benchmarks on all of them except IronRuby
