5:50 "it's not faster than C++" - Yes it is, the source is "Ranking Programming Languages by Energy Efficiency" which measures also time in a normalized way, and in that ranking Rust outperforms C++. In the most up-to-date measurements on the authors' website, Rust continues to outperform C++. So yes, Rust is faster than C++. However, C++ is the next fastest language, out of the 35 most popular as used by the paper. I have no dog in this fight, as I do not use either C++ nor Rust.

@NoX-512 The paper, when it was published, ranked Rust second place right behind C and ahead of C++ (top few languages in the Time measurement, in order and with multiplier for how-many-times-slower-than-C (rather, how many times slower than the first language, which happens to be C): C = 1.00, Rust = 1.04, C++ = 1.56, Ada = 1.85, Java = 1.89, Chapel = 2.14, Go = 2.83). However, the website has measurements that have been updated to 2021, I believe, from the 2017 date of publication of the paper. As it stands by those more recent measurements, Rust is now = 1.00, meaning it is just as fast as C. Indeed the Programming Language Shootout uses 10 algorithms to measure the speed difference between C and Rust, and each of those languages wins on 5 algorithms, making it a perfect tie for fastest language between C and Rust. C++ has not closed the gap (it kept being 1.56 times slower than C). Hence the old myth that "Because you can write C++ programs that is essentially C code" does not seem true. Also, a reminder that C++ is not a superset of C.

@NoX-512 As of now it's (1) the most trusted website in measuring language performance and (2) the most recent and most quoted paper measuring language performance both agreeing that Rust is as fast as C ans that both are noticeably faster than C++. I do not advise too big a grain of salt.

@NoX-512 "but which language is fastest, will be different for different use cases, and heavily dependent on the compiler used, and the programming techniques applied." You should learn some compiler theory. What you said there is not true. Your being under this wrong impression is clouding your understanding of this topic. Calling it "synthetic benchmarks" is not a counter-argument. Rust is as fast as C and both are faster than C++, your not wanting to accept that with non-argument excuses notwithstanding.

@NoX-512 If I were wrong you would be able to refute me, but you cannot, therefore I am right and you have sour grapes syndrome.
