Looks like some people think portage is faster with python3, is that
true? I have python3 set as main interpreter (for catching packages
failing to build/work with it), but my portage is merged without any
python* USE flag, I guess, it's still using python2, no?

If it's faster really, is python3 safe to use with portage or it's only
offered for testing purposes?

Thanks for the info :)
