### Testing Compiler Performance
The following commands will:
1. Build a set of projects from the compatibility test suite
2. Collect counters and timers reported by the compiler
3. Compare the obtained data to the baseline (stored in git) and HEAD (version of a compiler built without the PR changes)
4. Report the results in a pull request comment
Platform | Comment | Check Status
------------ | ------- | ------------
macOS platform | @swift-ci Please test compiler performance | Compiles full source compatibility test suite and measures compiler performance
macOS platform | @swift-ci Please smoke test compiler performance | Compiles a subset of source compatibility test suite and measures compiler performance
For the detailed explanation of how compiler performance is measured, please refer to [this document](https://github.com/apple/swift/blob/master/docs/CompilerPerformance.md).
