This is a good demonstration that autodetection-based CPU acceleration should be on by default. Also, it looks like several of your projects use zlib. You might take a look at zlib-rs, which is at this point faster than zlib-ng and easier to make use of from Rust. It's available as a flate2 backend. (Note that the folks working on zlib-rs are looking for funding for its development at the moment, if you're interested.)
