In the experiments,we compare the CloudBook with other methods, including servers
with sequential process (sequential server) and conventional Hadoop
platform, in the performance enhancement. Fig. 13 shows the performance
enhancement achieved by the proposed CloudBook solution, in
terms of the total execution time. In Fig. 13, the experimental tasks are
set from 2500 to 100,000. As Fig. 13 shows, the CloudBook obtains the
significant improvement when the number of tasks are increased When the number of tasks equals to 100,000, the performance can be
improved by 55%.
