Another UK data point: my daughter is in secondary school (= high school), not in a public-exam year. The school’s officially stated policy is that pupils in her year should expect 1.5-2.5 hours of homework per day. At no point has she been set anywhere near that much. The typical total is more like half an hour per day. (She’s very bright and it’s hard to know for sure how much time it’s meant to take; I’m guessing based on what she tells me.)
I’m fairly sure this varies a lot from school to school, even if we hold fixed what country, public-versus-private, etc.
