                 Key: JRUBY-2200
                 URL: http://jira.codehaus.org/browse/JRUBY-2200
             Project: JRuby
          Issue Type: Improvement
          Components: Performance
            Reporter: Tomasz Wegrzanowski
             Fix For: JRuby 1.1
         Attachments: making_base64_encode_on_instead_of_on2.diff

Array#pack("m") and therefore Base64.encode64 in JRuby is O(n^2) and very slow.
In MRI it's O(n) and very fast.
The attached patch makes JRuby Array#pack("m") and therefore Base64.encode64 
O(n) and very fast.

After applying the patch JRuby still passes all unit tests.
