That was not an article, that was an advertisement.

edit

I corrected it a little - it just said "how great Chez Scheme was", but:

- the language was at least apt to suggest SEVERAL INDEPENDENT benchmarks, while in reality it was only ONE SINGLE SERIES of benchmarks, by some random guy on the internet with some subjective set of samples (why not mention THAT?); and even that was 5 years ago, maybe that should be mentioned too;

- it was not said who was actually FASTER than Chez and on which place of how many Chez was to be found;

- it was "forgotten" to mention that Chez came out fast on the totally esoteric "Sun Blade 1500", while Petite totally lost out on the very common x86-architecture.

If you want to include benchmarks

I don't know if this qualifies, but this looks like a legit benchmark to me. It is also relatively recent and on x86: https://ecraven.github.io/r7rs-benchmarks/
