Awesome work! For comparison's sake have you timed ruby doing the same installs?
I also looked at rdoc a little bit and noticed ruby-based parsing. I am hoping if we profile it we can still find some super slow thing in JRuby which speeds this up... -Tom On Thu, 15 Jun 2006, Ola Bini defenestrated me: > > I shall not keep you waiting.
