I use the aggregation but these collections are unrelated.

What do you mean unrelated? You are getting every user and then getting the poll_votes for each of them in a loop; my suggestion is a single query that gets the poll_votes for every user.

I am getting data from 5 different collections. I see your point now - I can get the count for all users at once. This will be more efficient than the current solution where I call this count within a loop for each user separately. I need to think about behaviour when there will be tens of thousands of users and I need five such result sets.
