A compiler can't affect cpu utilization. The only thing that can cause that is (a) crafty doing I/O which only happens on table base probes, or for paging when hash is too large; (b) some other application stealing cycles via the O/S. A compiler can produce an inferior instruction stream, but it can't make the program less "cpu-bound".
