Different languages are optimizable for different algorithmic approaches, and what seems the same between two languages based on similar syntax may actually be semantically different so that behind the scenes you end up comparing apples and oranges. A deeper understanding of the differences between language implementations is needed than just the existence of similar syntactical forms if you want to perform an apples to apples comparison. In general, Ruby will tend to be slower than Java and C#, but how much slower depends on the specific form of your source code and the specific Ruby implementation you use -- and there may even be times when a Ruby operation might be faster than an equivalent in Java or C#. As I indicated above, though, some of that variance will depend on whether what looks the same syntactically might actually be very different behind the scenes. For instance, in some respects a Ruby symbol is more like a Java string primitive than a Ruby string (and working with strings in Ruby is typically much slower for execution time than working with symbols). --=20 Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ]
