Please do not forget provide your affiliation. Well, It may depend on: cutoff energy k-points symmetry tolerance number of atoms (modes) CPU's number network problem etc., etc., If you mean the same calculation takes considerably different time (on the same computer system) for the same q-point, I guess, it is a problem due to your system. If you mean time elapsed is different for different q-points that is normal.
