It sometimes is hard to write something specific in the commit message
about the actual performance increase.

For example, if a commit removes an O(N log2 N) algorithm and replaces
it with an O(1), you can't say there's an X% increase in performance
as the performance increase depends on the value of N.

Jelte did call me out for not mentioning enough detail about the
performance in c4ab7da60, but if I claimed any % of an increase, it
would have been specific to some workload.

What is the best way to communicate this stuff so it's easily
identifiable when you parse the commit messages?
