Ibuildings techPortal: Optimising MHVC Web Applications for Performance

On the Ibuildings techPortal there's a new tutorial from Sam de Freyssinet that follows up on a previous article he wrote about using HMVC (Hierarchical-Model-View-Controller). In this new article, he talks about some of the things you can do with that pattern to increase performance.

Hierarchical-MVC has been shown to make large web applications easier to scale out, but there is a price to pay- namely overall performance. This article will investigate ways of improving performance within HMVC web applications using asynchronous processing and some good old caching techniques. Predominantly this article will use examples written for the Kohana Framework; however all the concepts portrayed here could apply to any framework or web application.

He starts by pointing out what's wrong with the typical HMVC application - namely that the clean separation of code structure (the hierarchical part) costs the application in overall speed and memory usage. He suggests a simple technology for helping ease the load - caching as much information as possible, mostly in the HTTP client code since HMVC applications rely heavily on it. Code samples includd show how to implement this in a simple Kohana application.
