To test with more request, the 3rd case is 100 requests. Figure 13 shows that RCBA is still the most stable algorithm among the 5 ones. RCBA is only not good at the 40th and 50th requests, but it is just a bit smaller than the smallest. In this case, among the 50 request, the variant are much more, the graph shows like the zigzag image of all algorithms, this kind of requests fits the reality of cloud users. In this case, due to the small number of requests, we still see MaxMin the worst one. MinMin shows better than the 2nd case, and RoundRobin is still the stable one besides RCBA. To see how stable the proposed RCBA is, we continue with the 4th case that we use 1000 requests. |
