Are tags faster for filtering?


We are currently trying to improve our models. We have articles that is filtered based on which telco/sim is the user using while viewing our app.

The current filtering uses something like this.
'[in]': 'abfdjhgjfgey231435'
The category field is a reference field.

I wonder if using tags to filter our articles would be faster in terms of performance. Something like this:[all]: 'telcoAtt'
