This course has been created for PHP programmers and web site developers interested in PHP code optimization.
The course shows how to find a bottleneck and how to refactor or change the code in the appropriate way.
During this course participants will deal with real web page examples, which will be tracked, analysed and optimized.

What will you learn?
Performance tips all come with a shelf life that is linked to the particular technology to which they are applied. Once that technology changes or is no longer used, the tips become useless at best and harmful at worst. For this reason we have purposely designed a course that focuses on providing you with something more than just tricks to get the latest and greatest framework to meet your performance needs. One of the tools we aim to leave you with is a methodology that we've used over the years on a regular basis. This methodology has helped us quickly identify and solve hard performance issues.
The other equally important aspect of performance tuning is tooling. A good portion of the course focuses on a number of open source tools that we have found to be useful in our campaigns to stamp out performance bottlenecks.
Beyond methodology and tooling, we look at some of the fundementals of Java technology. This includes the inner workings of the Java memory management and HotSpot/JIT technologies.
