As an end user of Rust, I think the borrow checker seems slow because it's one of the last phases to run during vscode's real-time feedback. More than once I've been in the midst of a long refactoring session, and finally fix what I think is the very last syntax problem. But then the borrow checker finally gets to run, and then I learn about a whole new set of problems.
