So this would be limited by main memory bandwidth, if implemented correctly, but I doubt it even is limited by that right now (i.e. because it is apparently single threaded, and one core typically won't be able to saturate main men bandwidth). The author should measure this and find the active limit (instruction retire or mem bw); perhaps then he will find insight.
