the point that has been known for decades is not, "Switching from Node.js to Go gives you better performance," it is "switching from a high-level language to a low-level language gives you better performance." This point _has_ been known for decades, but new generations of programmers keep re-discovering it. (note: I am not critizing new programmers, I am one of them. in fact, having recently switched from python to rust, you could say I am one of the many re-discovering the performance joys of lower-level languages)

Those are just examples of a high-level language and a systems programming language though, and the expected result is the same as comparing Perl/Tcl/Python with C/C++, or whichever decades old variation of this topic you want to pick :)

Higher level languages generally being slower than lower level languages has been documented for decades.
