I'm not very up on about the chez integration into racket, but on it's own, chez is/was consistently at the top of scheme performance benchmarks in almost all areas - it's nearly 40y old with continuous improvements/research into performance throughout the history and was sold commercially for many years and well past the era where buying tools for software development is the default. This paper from 15 years ago should impress anyone interested in compiler design performance, esp. for weakly typed languages or lisps: https://legacy.cs.indiana.edu/~dyb/pubs/hocs.pdf https://legacy.cs.indiana.edu/~dyb/pubs/hocs.pdf
