Loading things concurrent isn’t always as good as it sounds. It’s possible it makes things lot worse. Just calling them sequentially and let different request basically do concurrent request to the database might be better because it’s more fair sharing of database resource between requests. We did this in the past and had to refactor our app away from it because one request would start lot of multiple data calls to database and block short request with only few database call that arrived little bit later. So I would think hard before doing this kind of “optimization”.
