I'd be careful about making that assertion. The benchmarks in Ruby 1.9 
are specific areas that Koichi has optimized to make 1.9 run them 
faster. There are other areas, especially as regards core classes and 
evaluated code, where 1.9 is no faster or even slower.

Not trying to rain on the parade, but even Koichi has recommended not 
taking the 1.9 benchmark numbers as indicative of overall performance.
