- N+1 problem will never be an issue with N1Loader gem
Interesting, I've just been researching Dataloader implementations for Ruby and have between trying to decide between GraphQL::Dataloader, graphql-batch and BatchLoader. I'll give this a look as well. Can you also make API calls inside the loaders?

- Avoiding N+1 Queries in Rails: Easy Performance Wins for Beginners
The bullet gem is designed to catch N+1 queries and notify you.

Use the Bullet gem to catch N+1s and unused includes
- Optimize Database Performance in Ruby on Rails and ActiveRecord
There are a few useful tools at your disposal to help identify and resolve N+1 problems. The first is simply looking at your server output; generally, this works pretty well, as N+1s are easy to spot. For a more assisted approach, the Bullet gem is a popular tool that automatically detects N+1s in applications and suggests ways to fix them. Another, arguably better option is prosopite, a less well-known option that generally provides better results with fewer false positives (and false negatives).
- Finding and optimizing N+1 queries on a relational database
I install the Bullet gem in every Rails project because it not only detects these N+1 queries but tells you how to fix them, helping to ensure they never even make it to production.

- Inherited rails app - what the hell are all these rack timeout lines in the log?
Without seeing more of the app, it's tough to say for certain, but one gem you might find helpful is the [bullet](https://github.com/flyerhzm/bullet) gem -- set this up in the app then start browsing around the app in development. If you have any N+1 queries or other minor optimizations that could be done it will inform you about them.

Getting rid of N+1 queries - This can help improve the speed of an app. The Bullet or Prosopite gems can give a lending hand here. The N+1 Dilemma — Bullet or Prosopite? entails a brief comparison of both.
- Understanding N and 1 queries problem
There's a Ruby gem called Bullet that identifies and warns developers about N+1 problems. You can also have it fail tests if detected.
I don't know if the approach is possible with every ORM or if it's just leveraging some Ruby perks, but I can't think of a good reason why you wouldn't use the equivalent everywhere.
