Attempt to perform intersect on input SHP layers with higher number of features hangs around 60% and never finish.

the vector geoprocessing tools of qgis (aka ftools) are known to be very weak with large/complex geometries. There are other tickets about this, and recently (after the las palmas dev meeting) also a lot of discussions about this matter. There is already a c++ implementation of such tools, in qgis enterprise, but it is not reverting to qgis soon, at least not in 2.14.
