Also string interning incurs a cost when creating strings which may or may not be worth it depending on the number of times you perform grouping/sorting on the data. To take this into account one would need to include the time needed to create strings from raw bytes, or to read a text file.

In [the previous thread](https://discourse.julialang.org/t/wip-faster-string-sort/7671/65) you showed a graph where Julia was as fast as R. What’s the difference with the new graph? Is it just `sort` vs. `sortperm`?
