of delay – It takes to load site with laravel

Good evening, I'm starting with laravel though, I'm facing a critical delay too .. tried with two templates and both took at the same time (on average), I wanted to hear from you, because I searched everywhere and did not find an answer. ..

To have a base, laravel takes 7.47s to load a file of 247KB.

In total, exact delay 23.17s

Does anyone know why of that screaming delay?
PS: The template is not heavy, for those who want to check:
This is the page / template in which it is delayed.

In case it has not been clear, just ask to add more information.
