Many words were spoken about the symfony framework, so we will take an action directly. We will briefly introduce the symfony framework for those who never heard about it. After the introduction we will go more deep into techniques dealing with performance optimization.

On an example project, build upon the symfony 1.4, using APC (Alternative PHP Cache) and XHProf (hierarchical profiler for PHP), we will demonstrate possibilities of logging, debugging and profiling of several application layers. Caching might come in the end. Visit our talk and you will meet symfony from another side.
