Why does Symfony 3 take so long to load?

Question

symfony

Delivered Symfony3 framework-standard-edition, I load app.php (prod), standard defaultController is loaded 300-400ms. I use php7, Symfony config is standard. Why so long?

Answer 1

For a production environment, 300-400ms is too much. In fact, even for a development environment with a complete rebuild of the caches, this is a bit too much. Check the creation dates of the files in the var/cache directory, if they change with each request - you are not in a production environment. If there is a debug console on the bottom of the page, you are not in a production environment either. Also check if the doctrine logger is enabled, it also eats a lot. As for doctrine caches, it makes sense to store them in memcached.
If nothing helps, look through xhprof what is taking so long for you.

Answer 2

Too long to sell.
Is debugging turned off?
is xdebug disabled?
is opcache enabled?
Is the computer up to date?
