For me the strange things are: - that std::min_element and std::max_element is faster as boost::minmax_element ...

Why does this surprise you? std::min() (or std::max) should be faster that boost::minmax(). boost::minmax() should be faster than subsequent invocation of std::min() and then std::max().

minmax_element is slower as 2 subsequent calls of min_element,max_element. This is suprising...
