Comparative study of application performance on virtual machine and physical machine

It is a well known fact that there exists a direct relationship between the availability of resource and application performance. Conversely, an application´s performance decreases with a dearth of resource availability. However it has to be noted that allocating a physical machine to service the application is clearly an overkill. This anomaly stems because resources are underutilized. With the advent of fast CPUs, it can easily be perceived how many cycles are wasted when a single application is run. Here is where virtualization comes to the rescue. Virtualization provides a perfect platform for an optimal use of resources by a fair share allocation of available resources to different applications. Towards this, multiple virtual machines (VMs) are employed with each application running on a VM. The aim of this paper is to analyse the performance of Jmeter on VMs and PMs. Additionally this paper also illustrates the performance of VMs that are allocated resources dynamically.
