Remember that they are two different languages with some similarities. Perl6 has really good support for making big apps I would say as it has really good OO support out of the box in addition to making FP concepts easy too. Perl5 has atrocious support baked in, but they have the excellent libraries that everyone uses to give them world class support for OO. Still, it feels more natural in Perl6.
On another note, Groovy is another great and fast language that runs on the JVM and works very well in the scripting space with a lot of DSLs for GUI, XML, DB...cool stuff.
But the same versioning issue exists for Apache Groovy (2 or 3 ?) that exists for Perl (5 or 6 ?). The Groovy PMC seem to be handling the issue, though, by slowing down the development of Groovy 3 to a crawl so it won't ever ship.
Oh, and calling Groovy "fast" is a bit of a stretch. It hardly matters anyway because scripting for classes written in Java doesn't need "fast".
