VM server, indicating performance scalability improvement with two virtual machines. Our results also revealed significant percentages in latency and bandwidth achievement by Oracle VM server which cannot be overlooked, despite some variances in results obtained from LMbench measurement.

INTRODUCTION Presently, many vendors like Intel, AMD, Sun Microsystems, and IBM are developing virtualization products which target markets with revenues in the billions and growing [3]. Server virtualization efficiently permits software to be separated from the physical hardware. With a secured server virtualized system, there is improvement on the availability of application and the isolation of processes. Server virtualization also has security setbacks, such as exploitable weaknesses in virtualization software, anomaly performance metrics with some benchmark devices, misconfigured virtual hosting platforms and guest operating systems [4]. However, apart from these diverse security threats, once the security controls for the virtual environment are slipshod, there is a greater possibility for infection. Server virtualization is a tool used to reduce the operational time and cost in today’ s puting but if done wrong it bees a security threat to the environment. This saving of time and resources allow businesses to devote more time to new opportunities rather than focusing on maintenance and management [5]. A salient feature of virtualization is scalability, which allows for growth in capacity, performance and availability of the virtualized system. There are many benchmarking tools designed to measure different performance characteristics. Examples include Swingbench for evaluating transactions per minute [6], LMbench for measuring work bandwidth and latency [7], Httperf for measuring web server performance [8] .This research, evaluates the performance and scalability of the Oracle database both in a virtualized and non virtualized environment. We use Swingbench and LMbench as benchmarking benchmarking tool has found prominent in performance evaluation. Swingbench is specifically designed to generate load and stress test an Oracle Database. Whereas, LMbench gives an i。
