What a coincidence. :) Just an hour ago I compared the performance of wild, mold, and (plain-old) ld on a C project I'm working on. 23 kloc and 172 files. Takes about 23.4 s of user time to compile with gcc+ld, 22.5 s with gcc+mold, and 21.8 s with gcc+wild. Which leads me to believe that link time shouldn't be that much of a problem for well-structured projects.
