There are two methods of powering a Web Application with Roadsend PHP:
Interpreted Web Applications are executed directly from the application source code - this is the way Zend PHP works. Roadsend can power interpreted web sites by installing the Roadsend PHP FastCGI interpreter.
Compiled Web Applications are converted to optimized machine code before they are run. The source code is no longer necessary and the application runs faster. Compiled web applications can be targeted for online, dedicated server use (via FastCGI) or stand alone, desktop use (via MicroServer).
