Which Mutex to use in this case (independent tasks, partially under contention)

• parking_lot

  7 2,765 6.8 Rust

  Compact and efficient synchronization primitives for Rust. Also provides an API for creating custom synchronization primitives.

  parking_lot still has an open issue #201: Heavily degraded performance while in extreme contention on some processors which reveals that parking_lot selfishly uses spinning locks under some circumstances to sacriice total system efficiency in the name of trying to improve its own latency. In my opinion, the only place spinning locks are excusable is fullscreen games and, even then, Linus Torvalds is of the opinion they're usually implemented wrong. (Issue 201 also includes a bunch of benchmark runs if you want to read through to figure out which one applies to the current shipping state of the codebase.)

  Hypothesis-like property testing for Rust

  

  Third, if you're opting out of a compile-time safety guarantee in the name of performance, test heavily (high-coverage unit tests, property testing, fuzzing, differential fuzzing, etc.) and make use of tools like Loom and Miri's runtime data race detector for unsafe code, which can catch stuff that is beyond the scope of the compiler's guarantees.
