Post installation

I have tested this at my local installation and there it worked. What could be the problem?

Hello,
from command line) in c:\xampp\htdocs I installed drush with this command
composer require drush/drush
To see how it works I type from c:\xampp\htdocs\sito\web
drush cc
I get back the warning that drush is not recognized as a command.
What am I doing wrong ?

I'm defining the structure of the taxonomy on which the whole project is based.
In terms of performance, both for administrators and for displaying content to users, is it better to have several vocabularies with relatively few terms or only one with a large number of terms? 
I would like to avoid both problems with the overview of the list of terms and (views) too slow queries and too many joins.

To get a rough idea, I have to decide whether to have 10 vocabularies with ~100 terms, or one vocabulary with ~1,000 terms.

Thank you for your suggestions
