The main difference you should care about esp. in web-applications such as ones built with Rails is true concurrency ("Global Interpreter Lock" free). When two threads are running (e.g. serving 2 user requests) with JRuby they are capable of running concurrently with...
What is the difference between “long”, “long long”, “long int”, and “long long int” in C++?
..., and long was 32; int could either be 16 or 32. Note for some platforms (esp. the 68000) both 16-bit and 32-bit int were quite common, and indeed some compilers had options to support either. Code which needed to be portable was thus expected to use short or long in preference to int.
