I'd begin with Emacs's built-in "M-x profiler-start". After invoking that, start the Helm loading command, and when it ends, invoke profiler-report. Post the resulting profile fully expanded, and maybe that will give some clues about what to examine next. It will also be useful to have a comparable measurement from GNU/Linux, so that we could compare the profiles and the elapsed times.
