Computer Science > Operating Systems [Submitted on 24 Aug 2026] Title:mold: A Massively Parallel Linker View PDF HTML (experimental)Abstract:Linking is a critical step in the software build process that combines compiled object files into a single executable or shared library. Despite decades of engineering effort, link times remain a significant bottleneck in the edit-compile-debug cycle, particularly for large C++ programs. Existing linkers exploit limited parallelism, leaving most CPU cores idle during linking. We present mold, a Unix/Linux linker that applies data parallelism systema
Community take
Wild linker benchmarks faster; mold blocked from enterprise shops by Linux-only stance.
