routing

there are so many php routers these days that any "fast" claims should probably be accompanied by benchmarks. routing is a fairly uncomplicated task and the speed difference will only become apparent at really high loads. http://c9s.github.io/Pux/ http://auraphp.com/packages/Aura.Router/ http://zaphpa.org/ http://toroweb.org/ https://github.com/dannyvankooten/PHP-Router https://github.com/symfony/Routing http://docs.phalconphp.com/en/latest/api/Phalcon_Mvc_Router....

Thanks for your answer. > When matching routes, symfony uses a lot of function calls for each route This is the slow UrlMatcher. The one used by default in the standard symfony edition generates code like this: https://github.com/symfony/Routing/blob/0ee25e6580bd4169c128... , and this code is used for matching instead.

Explain here: - Pux uses simpler data structure (indexed array) to store the patterns and flags. (In PHP internals, zend_hash_index_find is faster than zend_hash_find). - When matching routes, symfony uses a lot of function calls for each route: https://github.com/symfony/Routing/blob/master/Matcher/UrlMa... - Pux fetches the pattern from an indexed-array: https://github.com/c9s/Pux/blob/master/src/Pux/Mux.php#L189 - Pux separates static routes and dynamic routes automatically, Pux uses hash table to look up static routes without looping the whole route array. - Pux\Mux is written in C extension, method calls are faster! - With C extension, there is no class loading overhead. - Pux compiles routes to plain PHP array, the compiled routes can be loaded very fast. you don't need to call functions to register your routes before using it.

> Pux tries not to consume computation time to build all routes dynamically (like Symfony/Routing). Instead, Pux compiles your routes to plain PHP array for caching, the compiled routes can be loaded from cache very fast. symfony/routing compiles routes only once to PHP code ([1]), and then that generated code is used for matching all subsequent requests. (There are multiple route matchers, but the default one works like this.) It's amazing that Pux manages to be close to 50x times faster. How is this achieved ?

I don't know about the article. But the truth is that Symfony2 is built from a collection of independent components. And each component could be used independently in your app without a need to use symfony framework. Here is for example a link for a routing component: https://github.com/symfony/Routing
