I led the engineering org at Papa, a YC unicorn worth north of 1.5B by the time I left.
The amazing team did a great job with Elixir.
Want to know what was the bottleneck for our performance 99.99% of the time? It wasn’t Elixir. It was almost always Postgres query tuning that saved the day.
I think this may be the case for the vast majority of apps. Stop sorting large arrays in app code, let the database to the work. Elixir will get you very very far performance wise.
