The compilation model is vastly, vastly, vastly better than languages like C++ and C, though, and it does compile much faster than an equivalent C++ build (doesn't count if you download precompiled binaries of your c++ dependencies)
Is Python a fast language because it barely takes any time to compile the code? No obviously not.

There’s an alternate version of Rust with significantly faster compiler times, because while we cared about compile times when designing we always prioritized other values more. We never asked ourselves how this feature or implementation impacted compiler analysis time and there are several spots where something slightly different would have much faster compiler times, which people do care about. But had we spent time on that, we would have neglected other things and not been any more successful.

This is important, because most often during development you want fast compilation times more than you want fast code.
But some of it is implementation problems.
