Here is the benchmark suite:
https://github.com/elixir-dbvisor/sql_bench, couldn't find anything remotely close to this for Ecto, turns out that the enummerable protocol which ~SQL is leveraging to provide superior ergonomics has no real impact on performance, so we have fundamentally arrived at zero cost abstraction which is a pretty cool selling point from Elixir perspective. I didn't even think this was possible when I first started this project, I think we could properly build the best performaning web framework across langagues in Elixir with unmatched ergonomics and concurrency.
