Hmmm... Didn't realize this would make difference :) Thanks!

Well, I started doing these benchmarks after I've tried to rewrite parts 
of the project I'm working on in Ruby. The project is rather 
complicated, so it seemed as if Ruby's neat, clean syntax would make it 
easier to handle, but the performance was dreadful. Initially I tried 
1.8.7 that came natively with OS X Lion, then installed 1.9.3, without 
much difference in performance - it's still mostly multiple times slower 
than the Perl version I have :( The problem with Perl version, though, 
is that once it reaches certain limit - it becomes rather hard to manage 
(especially so if you focus on performance the most - there are tricks 
in Perl that make code run significantly faster, but make it virtually 
unreadable).
