Illustrative benchmarks

[hadley]

I think it would be useful to include a couple of illustrative benchmarks that show the benefits of duckdplyr. Maybe one where there's some optimisation that duckdb makes that substantially improves performance on an in memory dataset, and one where you're working with a dataset that wouldn't generally fit in memory so you couldn't even use dplyr.

Here is my blog post that has an example but of course there's more to do here: https://duckdb.org/2024/10/09/analyzing-open-government-data-with-duckplyr.html
