I just recently installed the this latest version of Wordpress (2.5.1) and quickly found it hanging (while trying to load a page) for as long as 40-50 seconds! I then proceeded to isolate the potential causes (database, custom fields, custom theme) and have since found out that something stinks in 2.5.1's core.

He details some of the steps he took to try to track down the bug - installing on another server, searching the web for others with the same issue. His suggestion?

Before you upgrade your old working installation of Wordpress, I would suggest that you test 2.5.1 in some other directory just to be sure it works with your server.

In my previous article, I announced that I would be documenting the process of developing a simple MVC framework. In this post I will go into a little more detail about each of the specific components of our MVC and will discuss the series of events which occur each time a page loads, otherwise known as the page load scenario.

He talks about how URIs work, the role of mod_rewrite, several of the objects involved (like the Front Controller, Request, Route and View) and how they all fit in with the custom Models, Views and Controllers the user could define.

It's time to learn a few other methods included with the DOM XML extension. Based upon this premise, in this fourth tutorial I'm going to show you how to get access to multiple nodes of an XML document, either for internal processing or simply for echoing to the browser.

They show you how to grab the collection of nodes to work with and how to grab data from an XML text file with load() and loadXML().

There are 4 relatively easy ways by which you can speed up the time it takes a browser to download a page. Following on from my post on joining CSS and JavaScript files, I have written a PHP script which will automatically do all of the above.

He gives example code of the class in action and includes some screenshots of the benchmarks from the YSlow Firefox extension showing the improvements.
