It likely won’t matter much here, but invoking cat is unnecessary.

   sort <file> | uniq -c | sort -n

will do the job just fine. GNU’s sort also has a few flags controlling buffer size and parallelism. Those may matter more (see https://www.gnu.org/software/coreutils/manual/html_node/sort...)

Thanks for sharing!

You're right that the `cat` is unnecessary - and removing it actually had some marginal gains to the naive solution. I've updated the benchmarks to show this

Cheers
