Depending on what you're trying to measure, there are several different approaches:
- If you want to see if a PR improves or regresses compiler performance:
- - The [rustc-perf](https://github.com/rust-lang-nursery/rustc-perf) project makes this easy and can be triggered to run on a PR via the `@rustc-perf` bot.
+ - The [rustc-perf](https://github.com/rust-lang/rustc-perf) project makes this easy and can be triggered to run on a PR via the `@rustc-perf` bot.
- If you want a medium-to-high level overview of where `rustc` is spending its time:
- The `-Zself-profile` flag and [measureme](https://github.com/rust-lang/measureme) tools offer a query-based approach to profiling.
