We compute four-point correlation functions of scaler composite operators in the N = 4 supercurrent multiplet at order g(4) using the N = 1 superfield formalism, We confirm the interpretation of short-distance logarithmic behaviours in terms of anomalous dimensions of unprotected operators exchanged in the intermediate channels and we determine the two-loop contribution to the anomalous dimension of the N = 4 Konishi supermultiplet.
