Sometimes security can block up quickly if there happen to be tour groups run by one of the German travel companies - the rest of the time it's very smooth.
In winter I would allow much more time for any road transport to reach the airport in case of snow conditions.
You are correct that security can occasionally be busy, even in the summer if you have some charter flights but even then you would be unlikely to miss your flight once you have checked in 1h10 before your flight and other people likely to check no earlier would probably also be held at security if that were the problem.
