(The "faster" bit isn't important; various reasons might have made C++ slower than Rust for this, but what is important is that perf was comparable)

What I questioned was Rusky's technical-sounding but apparently unsupported claim that "the benchmarks game's results are not very correlated with real-world performance." For Rusky to know he'd need some kind-of "real-world performance" measurements and a correlation coefficient - neither of which have been shown.
