Node.js vs. FuelPHP vs. Spring

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

FuelPHP is a fast, lightweight PHP 5.4 framework. In an age where frameworks are a dime a dozen, We believe that FuelPHP will stand out in the crowd. It will do this by combining all the things you love about the great frameworks out there, while getting rid of the bad.

A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
