David Lattimore investigates why Wild's linker benchmarks show substantially slower results compared to its own August 2026 benchmarks after Mold included Wild in their updated linker benchmarks. Key differences include filesystem configuration (tmpfs vs ext4) and the use of --no-fork flag, which significantly affect performance measurements. The author plans to adopt a mixed benchmarking approach going forward.
Background
Wild and Mold are two high-performance Rust-written linkers for Linux, competing as alternatives to traditional linkers like LLD. They are widely used in large-scale builds, particularly in the Chrome and Linux kernel communities.
