Here's an example of idiomatic Pandas taking 10 minutes while Polars takes 7 seconds: https://www.pola.rs/posts/the-expressions-api-in-polars-is-a...

I'm not saying that polars isn't faster. In fact in my other comment here I mention that polars is much better than pandas at what polars does (it's not a drop in replacement). I'm just saying that most of the times (not always, and in fact in those cases we've used polars to speed it up) that I've seen painfully slow pandas operations has been due to poorly formatted pandas code.
