            Bug ID: 281765
           Summary: llvm - ThinLTO never uses more than a single thread by
                    default
           Product: Base System
           Version: 14.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: diizzy@FreeBSD.org

Maybe I'm missing something obvious/intentional but according to upstream
documentation [1] it should default to one thread per physical core but at
least I have never seen that happen on various amd64 and aarch64 systems. A=
ddin
-Wl,--thinlto-jobs=3DN to LDFLAGS makes it work as expected though.
