skim-rs/skim v4.3.0 on GitHub

Performance improvements

This release brings a custom thread pool & coordinator shared between the reader & matcher (instead of a single-threaded reader and rayon for the matcher).

In practice, this makes skim up to 4x as fast as fzf with 100M items in our benchmarks, see below for details (note the logarithmic scales).
