  Awesome. I actually started writing notes for something like this the other day. Will read asap :) edit: Glad to see hashers at the top. This is one of the easiest wins you can get and it can be pretty significant. I see some stuff that could be added. `dyn` vs static dispatch, for example. Do I just open an issue somewhere? edit: Created issues.

  The "Profiling/Debug Info" chapter states that one needs to rebuild compiler and stdlib in order to profile the stdlib. If I understand correctly, this can be accomplished via flag '-Zbuild-std'.

    I didn't know about this. Thanks for the tip!

  The part where it says that parking_lot's Mutex is faster then std's is obsolete since 1.62.0 IIRC.
