Experience on Performance Evaluation with OGSA-DQP

OGSA-DQP is an open source service-based Distributed Query Processor; as such, it supports the evaluation of queries over collections of potentially remote data access and analysis services. As it operates over several layers of service-oriented infrastructure, one particular need (both among the developer team and the relevant community) has been to investigate the impact of the infrastructure layers, understand performance issues, identify bottlenecks and improve the response times of queries where possible. This paper conveys experiences gained in doing so, by describing the experiments carried out and presenting the results obtained.
