## AI overview

GitHub Copilot build performance for Windows now provides deterministic messages for optimization outcomes, including successful improvements, changes below the success threshold, unsuccessful changes, and builds that were too short to analyze. Successful results include baseline and final build times, measured improvement, and effects on iterative builds when applicable.

## Source excerpt

We know that slow builds are a consistent theme in feedback from C++ developers. Your feedback helped us to shape GitHub Copilot build performance for Windows, an agent that can trace your build, find bottlenecks, apply optimizations, and measure the result. When using the agent, the clearest outcome is a straightforward win. The agent changes [...] The post Clearer Build Optimization Results with GitHub Copilot appeared first on C++ Team Blog.
