From the manpage of mold-1.3.0, I get the impression mold is designed to scale up to 32 cores, but not more.

  man mold | rg -C2 32
       --threads
       --no-threads
               Use multiple threads.  By default, mold uses as many threads as the number of cores or 32, whichever is the smallest.  The reason why it is capped to 32 is because mold doesn't scale well beyond that point.  To use only one thread, pass --no-threads or --thread-count=1.

Is this correct or does the manpage need to be updated?
