One of my developers just sent me some truly incredible stats about Ruby 1.9 and its threading performance.



20 threads * 100,000 iterations

Ruby 1.9 = 1.54 s.

Ruby Enterprise = 3.01 s.

JRuby 1.1.2 = 5.82 s.

Jython 2.2.1 = 11.86 s.

Python 2.5.2 = 12.32 s.

Ruby 1.8.7 = 22.68



Since our attempt at testing Ruby as a crawler really wasn’t all that much slower than Python it could be really interesting to see what will happen with Ruby 1.9.
