Performance comparison of load/store and symmetric instruction set architectures

Is it true that a Load/Store architecture is both simpler and faster than a Symmetric architecture, or does the Symmetric architecture offer a potential performance advantage that can be realized by the use of additional hardware? In order to answer it quantitatively, we simulated two models that were equal in all aspects except the factor that we measure. We found that the Load/Store model executes 12% more instructions but only 4% more cycles.
