One of the more common problems that many organizations face is the perception of performance in their web applications. Or rather, the lack of it. With this presentation we will take a look at several different performance “best practices” and also look at some ways you can analyze what is happening on your server. Not only will we look at PHP, but we will look at several different links in the execution chain, such as the database, network latency, IO contention, CPU utilization, and network connectivity along with best practices/pit falls/fhings to consider, all of which can negatively or positively affect the performance of your web application.
