> Lots, naturally, but hash tables have many moving parts and performance is many-dimensional which is why I didn't include the raw data; it's voluminous and not always easy to interpret. Giving a single number as in 'now 20 % faster' is impossible if we want to stay honest, because there are so many different aspects, contexts and operations.

It doesn't have to be a single number.  Showing a series of separate
benchmarks is also fine.
