While the Linux I/O architecture is complex, a number of open source tools exist that make finding bottlenecks easier. These tools include traditional Unix utilities like "iostat", but they also include some tools that go deep into the block layer and give you information about major events in the life of every I/O operation.

First, we have to understand the structure of a Joomla Core site. Joomla's content management is broken down into two basic units, the Category and the Section. (show diagram of Joomla Core) The idea here is to take as large of an advantage as we can from Joomla Core, before we move to creating anything custom. The power of Joomla is in our ability to create a website quickly and without a huge software development effort. We're going to take these navigation trees (diagrams) from a failed web development effort and quickly align them into the Joomla structure, to take advantage of what is available in Core. As we'll see, not everything will fit into this structure, and we'll have to define some custom modules which will take care of the rest. ...

Do away with the pain of authentication schemes, do away with learning the foibles of multiple Web services, "select * from internet". Yahoo! Query Language (YQL) allows you to query Web services using familiar SQL-like sytnax. Not just ours though, you can query any web service using YQL, we should have called it Your Query Language.
