I did a few rudimentary benchmarking tests on in house real world data sets and strictyaml was approx 10X slower than PyYAML's yaml.load (w/ out calling out to libyaml) and yaml.safe_load.

I used the basic strictyaml.load function, without any schemas.

README page said speed is not a current priority, and that appears to be true.
