Are tags faster for filtering?

Hi!

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.
'fields.category.sys.id[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:
metadata.tags.sys.id[all]: 'telcoAtt'

Copying my response from our conversation in Contentful Community Slack here :wink:

Contentful’s Tags FAQ does mention that Tags tend to produce faster results when filtering content. See “Can I use tags in search?” :+1:
