Measuring and improving the performance of your PHP application is critical to giving your customers a great experience. To get a realistic view of where the time spent in PHP is actually going, you need to profile your code. XHProf is an open source, low overhead, robust profiling tool for PHP. This talk will explain how to install it, leverage its most important features, and solve the kinds of problems that XHProf can help identify. XHProf has a browser based UI, which makes it extremely easy to use and to share code profiles with coworkers. I will be demoing various traces, talking about PHP micro-optimizations, and showing you how to quickly drill down and find the slowest parts of your site. By using XHProf to identify the big wins, you can spend less time optimizing and more time building new features. You will come away from this talk with a working knowledge of XHProf, and the ability to get it up and running in your environment in minutes.
