Differences Between Ruby Virtual Machines

Question

What are the advantages / disadvantages of basic Ruby VMs (things like features, compatibility, performance, and quirks?) I know that there are also some bonus features, such as the ability to use Java interfaces through JRuby. This would also be useful to note. Does any VM have a distinct advantage at this stage and in what contexts?

Answer 1

I used both Matz Ruby and JRuby, and they solve different problems. If you are developing a direct Ruby or Rails application, then this will probably be enough, but if there are several powerful Java libraries that would help a lot, then JRuby might be useful.
