Virtual machine technology is being widely deployed in enterprise environment as a means of server consolidation. There are needs of measuring performance that is provided in virtual machine environment.
In this paper, I focused on the problem that the accuracy of the time provided in virtual machines is not good for measuring the processing time.
I first observed the accuracy of time keeping in virtual machine through the network comparing high precision clock. From this observation, the clock in the virtual machine has large jitter compared to real ones. Next, I proposed a method which corrects the time used by benchmark in virtual machine by referring the time in a real machine.
To evaluate the effectiveness of this method, I conducted experiment with a micro benchmark tool, and measured the average of the time error and its variance. From this experience, I concluded that my proposal can improve the accuracy and the confidence of the benchmark score in the virtual machine environment. |
