Presentation title: High Performance PHP

Abstract:
This presentation treats about design and implementation of highly efficient PHP applications. Based on his experience and expertise provided by the developers and architects from companies like Digg, Yahoo, Facebook, Friendster and Flickr he will present techniques which ensure sufficient performance and efficiency in applications. Presented examples will concern both the PHP code and solutions at the architectural level. He will also describe the most frequently used nowadays software stacks configurations, that use PHP. During this presentation you will also hear about techniques and tools, which are helpful during application performance testing, including code profiling and finding potential bottlenecks.

As a summary of the presentation Mariusz will present 10 best and worst techniques/practices affecting the performance of PHP, which you may encounter as an architect and PHP developer. At the end will also include a brief session of live coding demo showing the effects discussed earlier on optimization of operations, for example, we will see a simple application based on Zend Framework or Symfony, and relational database.
