Ruby is generally recognized as being twice as slow as Python Am I the only one who has never heard of this? I'd definitely be curious to see some relevant be

  It varies naturally per application. When I was doing a little prototyping before deciding to write the core of our ranking algorithm in C++ I took the tightest inner loop and compared C++, Java, Python, Ruby and Perl. For floating point numerics and lots of list traversal the results were: - C++ | baseline - Java | 2.5x baseline - Perl | 4.5x baseline - Python | 6x baseline - Ruby | 14x baseline As a result, we're using C++ where it really matters, Java where it kind of matters and Ruby where it doesn't. This was more than a year ago though, so any performance gains since then naturally aren't included.

  ruby 1.8 is slower than python, but ruby 1.9 should be on par with it.
