I'd say 'not only'. As an example, YARV would allow compilation of ruby
to c code so that people could get slightly obfuscated libraries, a
thing that is often asked. Or they could provide native OS threading.
But in general I guess is mostly a matter of performance :)

Well, each different project has different aims.
Say, the Cardinal guys are writing a ruby2parrot compiler because it
will allow you to use every perl module out there and there are /lots/
(not only this reason but even this).
JRuby allows you to use ruby in places where you could not use C
libraries (i.e. I'm not aware of any C/C++ application server :)

there are just a bunch of different reasons :)
