Yeah I have to second UnfortunateShort. Benchmarking papers are on average very bad, often because they're trying to push a particular idea or product and are very biased, or because they're like "my first benchmark" and done by people who don't know what they're doing.

A classic one that gets referenced a lot is "Energy Efficiency Across Programming Languages" I which the authors seriously benchmarked programs from the very heavily gamed Computer Language Benchmarks Game, and concluded among other things that JavaScript is much more energy efficient than Typescript.

The only realistic way to benchmark different languages is to take implementations that weren't written to be fast in a benchmark. For example Rosetta Code, or maybe leetcode.com solutions.

Or to do it yourself. But that requires you to be experienced in many languages.

Difficult for obvious reasons.
