I made a build profiler to understand Bun’s compile times
TL;DR
buildprof is an open-source build profiling tool that visualizes compile times for software on Linux, helping developers identify optimization opportunities. It reveals inefficiencies like poor parallelism and redundant tasks, making it easier to enhance build performance.
✦ Why It Matters
Use buildprof to analyze your build processes and identify specific areas for optimization today.
Key Takeaways
- Run buildprof with your build commands to visualize compile times.
- Investigate linker performance to identify bottlenecks in builds.
- Consider restructuring code for better parallelism in builds.
- Optimize LTO settings to improve build performance significantly.
How It Works
Buildprof uses ptrace to trace process execution during builds, capturing the start and end times of each subprocess. It organizes this data into a timeline, allowing users to visualize the entire build process, including dependencies and file interactions.
This approach is build-system agnostic, meaning it can work with various build tools like Cargo, Ninja, and Make.
