Jonathan Keane updated ARROW-14249:
-----------------------------------
Description:
It looks like there was a slowdown in our dataframe-to-table benchmark after
Arrow-13164.
I'm a bit surprised since that PR is about arrow -> R conversion (though there
might be some crossover).
Here's a recent conbench link that shows the the regression
https://conbench.ursa.dev/benchmarks/8533b3e9ea654bcea8ccd1fe448861ba/
It looks like it happens with types: integer, float, and dict, but not strings
