I did my PhD in The Netherlands. In my field (computational linguistics), the majority of people finished within the allotted four years. The working conditions are good: PhDs are generally employed as regular employees with vacation money and 13th month. The teaching duties were very light (typically TAing and later teaching one 7-week course), giving you a lot of time to focus on research.
