Add route caching

[kolos]

Use route cache automatically the same way as the config cached.

It saves ~3ms on every request for me.

Thanks that sounds good to me, any idea how much time it adds to cold starts?

[kolos]

Running 'php artisan route:cache' adds about 300ms to the cold start (tested on x64 / 1024M)

[mnapoli]

Status update: want to test this myself in a real project too, +300ms to the cold start is not negligible, even to get -3ms on warm invokes.

The alternative for people interested in optimizing performance is to cache routes before deploying (https://mnapoli.fr/optimizing-laravel-aws-lambda), which maybe makes more sense here.

Shouldn't the route caching happen as part of the build process?

[mnapoli]

Yes exactly my point

[kolos]

Well, if you know that you should (and can) run route:cache before deploying, it has no effect for you. Otherwise, it’s done automatically, with the benefit of faster responses.

I agree that it should be part of the build process, I do it now too :)
