Analysis: Do all the protocols have the same miss rate and same bus traffic? Which is the coherence protocol with the best miss rate and bus traffic? And which does it have the worst? In particular, is the miss rate the same for the MSI and MESI protocols? Why? Do you think that the results and conclusions obtained with these experiments are of general application or they may change depending on the used benchmarks? In conclusion, does the use of a concrete cache coherence protocol improve the multiprocessor system performance? Why? Are the conclusions you obtain similar to the previous ones for the miss rate?
