Clearing cache takes "long time" I am absolutely new in Drupal. I am trying to set up my first "Hello world" module and I am playing with it.
Every time I clear cache using Drupal Console, it takes 15 seconds, which is an eternity for me. 

Is this normal, or did I need to change setting?

This is the output of drupal site:status.

Yes, WAMP is not a good environment for Drupal 8. Use a different OS in a virtual machine. Either a Linux VM built from scratch or by a tool like Drupal VM, or a docker based tool like DDEV, Docksal, and Lando.

Which one to choose would be opinion based. Consider not only performance, but also that debugging is most effective, when the dev environment is as close to production as possible.
