PHP UK Conference 2014 - Ricard Clau - Scaling with Symfony2

This talk addresses the common misconceptions surrounding Symfony2, specifically the beliefs that it is overly complex for small websites and too slow for large projects. The speaker demonstrates various techniques to enhance performance and scalability for high-traffic applications using Symfony2. Key topics include system configurations, autoload optimization, profiling with xDebug and XHProf, and the comparison between SQL and NoSQL databases. Additionally, the speaker shares practical experiences and solutions derived from working in high-traffic environments such as Hailo, Privalia, Ulabox, Emagister, and SocialPoint.
