When you do

php artisan route:cache

A file like bootstrap\cache\routes-v7.php gets created holding all your routes from routes\*.php which are contained in Route methods that weight some calculation cost on your server each time you send a request to figure what to do for the current route.

Quoting from bootstrap\cache\routes-v7.php comments:

This allows us to instantaneously load the entire route map into the router.

Important:

• This cache file doesn't get auto updates and doesn't exist in a fresh project.
• This cache takes precedence over routes\*.php files.
• The bootstrap\cache folder is ignored by default by git.

So everytime you push a new version of your project to production you need to run php artisan route:cache.

On dev environment it is better to have no cache and ensure that by running php artisan route:clear.

Note that the optimize command was removed from the framework then added back.
