This question was asked last time the author posted this few months ago. I’m surprised they didn’t update the benchmarks. Kind of makes me think Vaex is faster.

The benchmarks are hosted by H2oAI, not by the polars team. Vaex is not in that benchmark.

I don't believe Vaex would be faster though. They aim at larger than RAM data processing, not maximum in-memory performance like we do.

That's the real question
