A few days ago, there was a story showing that it was twice as fast to compile Rust compared to the 2019 Macbook Pro: https://news.ycombinator.com/item?id=25126394

Since Rust is LLVM-based, there should be a substantial performance improvement for Clang as well.

Was that a full parallel build (using all available cores)?

Because that's what counts for me, as a developer.

I believe so, as cargo defaults to the number of cores, as per this issue: https://github.com/rust-lang/cargo/issues/2805

For what it's worth, this guy noticed a nearly 2x speedup in compiling OpenSSL, which is C code, so I assume GCC or Clang: https://twitter.com/sandofsky/status/1331732592958214145

This suggests, though it does not prove, that the performance improvement for code compilation is likely not exclusive to a single language.
