Slower execution in 1.9 mode
----------------------------
Key: JRUBY-5882
URL: http://jira.codehaus.org/browse/JRUBY-5882
Project: JRuby
Issue Type: Bug
Components: Performance, Ruby 1.9.2
Affects Versions: JRuby 1.6.2
Reporter: Charles Oliver Nutter
This is an example provided by @launchany on Twitter:

It appears to run a bit slower in 1.9 mode than 1.8 mode. After reducing the
benchmark a bit, I did find that Array#join is slower, perhaps because it does
not precalculate the size of the string. There may be other cases here that can
be improved.
