I’m starting to believe that one of the reasons why Rust is perceived to compile more slowly than C++ is that Rust *forces* use of “modern C++” idioms everywhere, while industrial C++ tends to be more C-like than C++ fans want to admit.

Have you tried to build the rust compiler on a machine with a large number of cores? I did, with 72 cores. The result was not nice. Most of the time was spent with less than 5 cores in use.

Well, certainly we can do better with parallelism, but most of the complaints we get aren’t from 72 core systems :)
