Ruby 2 test drive

Ruby 2 is fast! . First experience of running some of my scripts in Ruby 2 was: WOW !!! .

Ruby 2.0.0-p0 is barely out. I was wating for it to appear on RVM radar and today tried it finally. And ... as I said WOW !!!

Look at the numbers below. It's not what you can call a scientific approach for benchmarking, but demonstrates main idea well enough.

Running same small script in 2 Ruby revisions. Ususally second run is faster since some libraries are already preloaded in memory.

Can you see the difference?
