@rastilin oh yeah, I remember that one. The C++ code they used was pretty bad, they were writing C++ as if it were Java and taking a bunch of overhead. Expect that C++ is generally between Rust and C in performance (Rust advantage here being not following calling convention that C++ must abide too to just compile, C++ advantage being not taking 6 million years to compile the 24 million lines of the codebase)
