N2 - For d pairwise commuting automorphisms (flows) of a probability space, ergodic averages over parallelepipeds are considered. It is shown that the maximum rate of their convergence in the Lp-norm is (Formula presented.). A spectral criterion is also obtained for the maximum convergence rate in the L2-norm.
