IMHO, . it is stated in the benchmark when a framework test uses an ORM or "raw" pdo/whatever for db request. Things like Doctrine are elegant and smart ,but let's face it,they are so slow. PHP is not JAVA. Hibernate may be fast on JAVA but Doctrine is hardly (fast)... Symfony Laravele and Silex share the same http-kernel & event-dispatcher. Laravele and Silex however can use closures for controllers and filters/middleware, Maybe that's why there are faster. Classes are expensive in PHP , since PHP is not OO centric and classes are merely a add-on. Bootstraping Symfony means creating an insane number of objects. There are things that could be done about it. I'm sure PHP frameworks are so slow because of the abuse of class hierarchy.
