Speed of filtered queries with a lot of (ACF) data

When we have CPT’s with let’s say: 5K + posts and a lot of standard ACF fields within those posts.
How fast is the way Cwicly works with filters in such a case?

Assuming the query must be set to ‘frontend rendering’, I don’t know much about the exact pro and con difference with serverside rendering is such a case.

For example: I see wpgridbuilder can use special caching (which is normally not possible with frontend rendering I think?) and Cwicly does not. wpgridbuilder is really fast
