  • Performance Evaluation of Oracle VM Server Virtualization Software 64 Bit Linux Environment
    2011 Third International Workshop on Security Measurements and Metrics, 2011
    Co-Authors: Ibidokun Emmanuel Tope, Pavol Zavarsky, Ron Ruhl, Dale Lindskog
    Abstract:

    Server Virtualization has created some growing problems and disorder, such as unresponsive virtualized system, crashed virtualized Server, misconfigured virtual hosting platforms, performance tuning and erratic performance metrics with some benchmark tools. This research analyzed the performance of Oracle VM Server Virtualization software against that of bare-metal Server environment. It also examined scalability offered by Oracle VM and its operation for supporting high volume transactions. Two open suite benchmark tools Swingbench and LMbench were used to measure performance. The Swingbench was also used to measure scalability. 30 and 50 active users were used for the performance evaluation. We discovered from our Swingbench results that Oracle database performance in a single Oracle VM resulted in 4% and 8% overhead for 30 and 50 active users respectively. Performance metrics of 75% and 87% were obtained with 30 and 50 active users correspondingly in dual Oracle VM Server; an indication of performance scalability improvement with two virtual machines. Our results also revealed Oracle VM Server achieved significant percentages in latency and bandwidth that cannot be neglected, despite some adrift results obtained from LMbench measurement.

  • performability analysis of i o bound application on container based Server Virtualization cluster
    International Symposium on Computers and Communications, 2014
    Co-Authors: Erico Guedes, Luis E T Silva, Paulo Maciel
    Abstract:

    Use of Server Virtualization for providing applications produces overloads that degrade the performance of provided systems. The use of container-based Virtualization enabled a narrowing of this overload. On this work, we go a step forward and demonstrate how a broad tuning combination of several performance factors concerning to web cache Server - the I/O bound application analysed - to file system and to operating system, led to a higher performance of proposed cluster, when it is executed on a container-based operating system Virtualization environment. Availability and performance similarity of web cache service, under non-virtualized and virtualized systems, were evaluated when submitted to proposed web workload. Results reveal that web cache service provided under virtual environment, without unresponsiveness fails due to overload, i. e., with high availability, presents a 6% higher hit ratio and a 21.4% lower response time than those observed on non-virtualized environments.
