C++ sort vector vs vector keyed on double member variable

QUESTION

C++ sort vector vs vector keyed on double member variable

Asked 2017-Jun-23 at 15:59

I have a vector of custom objects I'm sorting and noticed that the sort took a bit longer than expected. I decided to look further into it and adapted the code from this sort benchmark where instead of vector, I'm sorting a vector. The result is that it takes about 2.5 times longer to sort the vector of custom objects, measured using boost::chrono::steady_clock as in the original benchmark code. This doesn't really make sense to me since the key is the same and the memory is already allocated by the time sorting starts. Why is that and does this affect other operations on such a vector, for example binary_search?

The difference is not due to allocations taking place. The size of the vector doesnt change while sorting, so there are no allocations. However, sort has to copy the elements around to put them in the right place. And it shouldnt be too surprising that copying a double, 3 strings and an int takes more time than copying a single double.
