When rustc explodes (or: how to profile the compiler to explain exponential build times)

  Firefox Profiler — Web app for Firefox performance analysis

  

I'm having trouble using https://profiler.firefox.com/ though - I've tried uploading the output of perf script -F +pid as described in the docs you linked but I keep hitting "Error: Unserializing the profile failed: SyntaxError: Unexpected token r in JSON at position 11", which makes me think it wants a JSON file? But uploading a chrome_profiler.json style profile also fails.

I think it's worth pointing out you should just be able to do cargo install --git https://github.com/koute/not-perf instead. Wonder why they didn't put that in the README.
