When optimizing websites and web applications for performance, one of the top thing you should do is shifting the load of data processing from server side to the client end.
There are a number of simple ways to achieve it, for example, you can do it with simple JavaScript just as Backbone.js and Spine are doing it. Not only do they provide a lot of great features, but they are also compact (3.9kb and 2K respectively when compressed). Installation (including the hosting system) is just a matter of copying the Javascript sources. So there is no need to install any server-side scripting software whatsoever.
To get started, try csonV.js and see how this tiny JavaScript can fetch relational CSV data at client-side just like JSON for performance optimization.
