How I made Rustdoc 33% faster in one week

说明与用途

通过优化 Rustdoc，构建时间在一周内减少了 33%，提升了开发者效率。

问题

Rustdoc was taking too long to generate documentation for large Rust projects, impacting developer productivity.

结果

By profiling, identifying, and optimizing critical code paths in Rustdoc, the author achieved a 33% reduction in build times within a single week.

工作流

• Profile Rustdoc execution to identify hotspots
• Analyze profiler output to pinpoint the most expensive functions
• Refactor or optimize the identified code paths
• Rebuild and benchmark Rustdoc to confirm performance gains
• Iterate until desired speedup is achieved
