Abstract Möller scattering and Bhabha scattering on noncommutative (NC) space--time is restudied. It is shown that the NC correction of scattering sections is not monotonic enhancement with total energy of colliding electrons, that there is an optimum collision energy to perform the greatest NC correction. Surprisingly, there is a linear relation between NC quantum electrodynamics threshold energy and the optimum collision energy.
