During analysis of SERVER-676 we identified that stable_sort as used in the sorter can be replaced with a normal sort. This would relax requirements imposed on the sorting and use a potentially different algorithm.
Additionally, we found that the NoLimit sorter uses a deque instead of a normal vector with a reserved capacity that would offer better memory locality.
A rough patch that implemented the changes mentioned here yielded a very significant improvement in index builds.
