Is map faster than array?

Also, although the map is O(log N), the big-O conceals a relatively large constant factor, at least for the std::map implementation, in my experience. I would not be surprised to find that the array approach is faster in this case, but again the only way to know for sure is to measure.

Is unordered map faster than map?

As you can see, using the unordered_map is substantially faster than the map implementation, even for small numbers of elements… Notice that as the regular map contains more elements, the insertion performance becomes slower. At 8M elements, the cost to insert into a map is 4x that of inserting into an unordered map.
