| Abstract | The design of autonomic systems often relies on representative benchmarks for evaluating system performance and scalability. Despite the fact that experimental observations have established that burstiness is a common workload characteristic that has deleterious effects on user-perceived performance, existing client-server benchmarks do not provide mechanisms for injecting burstiness into the workload. In this paper, we introduce a new methodology for generating workloads that emulate the temporal surge phenomenon in a controllable way, thus provide a mechanism that enables testing and evaluation of client-server system performance under reproducible bursty workloads. This new methodology allows to inject different amounts of burstiness into the arrival stream using the index of dispersion, a single parameter that is as simple to use as a turnable knob. We exemplify the effectiveness of this new methodology by introducing a new module into the TPC-W, a benchmark that is routinely used for capacity planning of e-commerce systems. This new module injects burstiness into the arrival process of clients in a controllable manner, and hence, enables understanding system performance degradation due to burstiness. Detailed experimentation on a real system shows that this benchmark modification can stress the system under different degrees of burstiness, making a strong case for the usefulness of this modification for capacity planning of autonomic systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
