symfony非常慢

Question

When I do an symfony2 application, a website, the website is very slow. I don't understand why. Have you any tips to find why?

For example:

Login with FOS, it take 7 seconds. For open another page it takes 8 seconds. It's the same in my web-hosting server or in local.

Answer 1

1. you should enable cache extension required by Symfony2 i.e. APC 3.0.17+ (or another opcode cache needs to be installed). Full documentation can be read here: http://symfony.com/doc/current/reference/requirements.html

2. Other tip is to use app.php i.e. production environment to avoid re-building symfony cache.

3. You can also enable Doctrine cache: Read Doc
