Testing the performance of a variety of (mostly interpreted) languages. With code from http://izumi.plan99.net/blog/index.php/2008/01/17/ruby-vs-php-performance/

Yes, it could, but that's not relevant. The code in these tests is intended to determine (roughly) how languages compare when performing the same kinds of primitive operations - array shifting, recursion, enumeration, etc. Thus, the goal is not to have the fastest algorithm, but to have the same algorithm in each language.

C++ compiled with "g++ -O2 test.cpp"
