Clearer Build Optimization Results with GitHub Copilot

This article discusses improvements in GitHub Copilot's build performance for Windows, focusing on clearer result messages that help C++ developers understand optimization outcomes. The new experience aims to provide deterministic results and better insights into build optimizations.

From the article

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 your project, rebuilds it, and shows how your build is made faster. Sometimes, a change may make a clean rebuild slightly slower while improving the incremental builds you run throughout the day. At other times, we also observed that optimizations may help without reaching the agent’s improvement threshold. In addition, the project may already be well tuned, leaving the agent without a measurable improvement to make. Thanks to your feedback, we…
