bullet VS RVM

Rails has Bullet[0] to help identify and warn you against N+1

Does Django have anything active? Quick search revealed nplusone[1] but its been dead since 2018.

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.

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.

You might consider adding the bullet gem as a development requirement and see what it tells you, it's generally pretty good at spotting n-queries and letting you know how to fix them.

As a Rails developer, recently I found Bullet [0] which helps massively in dealing with eager loading. For some reason I expected the framework to manage this sort of thing for me, even when Rails actually does a ton out of the box already. Only while refactoring I picked up on queries dragging performance. Oh well...

This is good advice, it'll likely pick out some glaring issues right away. I would generally recommend looking at DB queries here too and recommend Bullet, but most software like DataDog, AppSignal etc will often also point N+1 and issues like it out.

In order to find all those N + 1 queries that are slowing down in your application, the community recommends using the Bullet gem.

After googling it seems this is what I can find on GitHub issues which appears to be the most recent thread on the issue, or a similar issue.

rvm (probably the most used manager)

One suggestion would be to setup your install based on a development environment using git and a Ruby version manager like rvm or rbenv to allows you to setup a user controlled gemset and execution path.

If you're using rvm, then the rvm repository.

For my local machine, I use RVM (head). Other options are rbenv and asdf.

You can use tools like rbenv(https://github.com/rbenv/rbenv) and rvm(https://rvm.io/) to be able install and easily switch between different ruby versions

It depends how you install it. If you install it globally then it will work for all your projects. Are you using rvm for ruby version and gemset management? https://rvm.io/
