Why does Laravel 5 take a long time to open a page?

Question

Laravel

Laravel opens the page for a very long time, the debugger shows:

In errors

Tell me what the error is and why the page takes a long time to open
If you refresh the page immediately after that, then everything is fine, and after 5 minutes it may take a long time to load again

Answer 1

The first thing that comes to mind is Blade compilation
Or data hashing

Answer 2

Everything is written there, the error is here
https://github.com/laravel/framework/blob/5.2/src/...
So your $driver variable is empty. So you have a problem in the config for queues
in .env, this is QUEUE_DRIVER
and in the config/queue.php folder.
The second problem is also with the config (they probably also try to send a letter because of this delay). Look at what you messed up, try to roll back the configs.
