Ruby YJIT is slower by multiple orders of magnitude if we look at more than a single constructed example.

In addition, the blog post measures the cost of avoiding doing the interop, which allows wins as the compiler improves in the case of short-lived calls implemented in a native component.

This, however, is not exclusive to Ruby and statically typed JIT or AOT compiled languages benefit from this to a much higher extent.
