While this feels like common knowledge, I’m willing to bet you’ve learned extensively why you should profile everything when it comes to performance.

I remember my engineering manager was freaking out over me using strings instead of symbols because they’re less performant, meanwhile he didn’t know to add indexes to fks lmao.

He clearly cares about performance! Just never came to understand relational databases, which was my day 1 obsession. And doesn’t know how to profile the entire thing to make sure he’s stressing over the things with the largest effect size.

Anyway he got fired and works as a systems guy now. Happy for him lol.
