Ban 1+N in Django
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.

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.

Help with N+1 problem.
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.

Understanding and Fixing N+1 Query
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...

How do you find the cause of slowness in your app?
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.

Supercharged table component built with ViewComponent
When searching for examples of table components built with the ViewComponent gem, I was surprised to find none. After some inquiries, I came across examples that worked like this:

Vanilla Rails view components with partials | Stanko K.R.
I used to do "pure ruby" approach to that -- but basically wound up realizing I was re-inventing github's view_component. Their design goals were similar enough to what I was trying to do, that it made more sense just to use that, rather than try to re-invent it myself.
