Probably depends on the region. In my country, the church i attended to had three masses during the week and i think 6 (back to back all day) during Sundays. This was only one of three churches within a walking distance, and the (mid-small) city probably had around 10-15.

Which is expected, since every adult was expected to go to church every Sunday, and many people, especially elderly, went during the week. Also there were four or five priests, and only Sunday masses has more than one attending at once, so the load probably wasn't that large as I make it sound.

There are also regions where due to diversity of congregations, masses are held in multiple languages at the same church.
