Energy efficiency is a very important issue to keep the "Green" Earth, especially in recent years. We have to save the energy consumption anywhere and anytime, including a large set of servers, such as servers in the Google company. In our research, we mainly consider one important energy-electric power. In our previous work, we discussed the difference energy model in cluster servers, and also we proposed a load allocation algorithm for the routers to optimize the performance of web server and to minimize the power consumption in the meantime. This paper mainly evaluated the performance of our proposed approach. The simulation results demonstrate the performance of our load allocation method could satisfy the users' requirement of the response time and also save electric power consumption.
