> Converting dozens of programs to C or Rust to improve performance 10-100x.<p>Nitpick - switching from C to Rust is probably <i>not</i> responsible for that performance boost. If you compiled that C code with Clang and LLVM it would probably still generate similar IR optimizations. If you're seeing 100x speedups going from C to Rust then I'd kill to see what your gcc makefile looked like...
