Fwiw, an entry-level tenured professor in France has to teach about 200 hours/year. This is a bit daunting the first year, but as you gain experience it's not that hard. Notice that this also includes hours for mentoring undergrad interns, masters students, etc. So if you are active in research, it's quite easy to cover nearly half of this teaching load for "free", thanks to students that want to work with you in your little projects. It's an awesome environment to be honest!
