Olio is a is a web2.0 toolkit to help evaluate the suitability, functionality and performance of web technologies. Olio defines an example web2.0 application ( an events site somewhat like yahoo.com/upcoming) and provides three initial implementations : PHP, Java EE and RubyOnRails (ROR). The toolkit also defines ways to drive load against the application in order to measure performance.

We encourage alternate implementations of the application by either completely re-writing the application using a different language (say python), higher-level frameworks (such as CakePHP)
