Were you working on a C/C++ project, out of curiosity? Of the two projects I've meaningfully benchmarked gold on, one was written in Rust and one was written in Go. I can believe that the Rust/Go toolchains make life difficult enough for gold that there is less of a speedup realized.

And yeah, the `--incremental` support in gold is definitely very exciting. Unfortunately it is not complete enough that I've been able to use it on any of the projects where it would matter. Part of what gets me so excited about having first-class support in Zig is that it will work end-to-end, and adjust folks' expectations of how fast linking should be. Then those folks will go demand the same linking speeds of their C/C++/Rust/Go projects.

Building incremental support into LLVM/gcc/gold is definitely the long-term answer, but building an end-to-end incremental toolchain in Zig from scratch to prove the concept makes a ton of sense.
