This paper describes the experiences of the OGSA-DAI team in profiling and benchmarking components of the OGSA-DAI database access middleware built using the Open Grid Services Infrastructure and the emerging Database Access and Integration Services Global Grid Forum recommendations. The profiling approach and the tools used are described. A number of areas of concern are then analysed in detail. In particular, the analysis focuses on running database queries, creating Document Object Model objects, utilising Globus Toolkit Grid Security Infrastructure mechanisms, validating XML against XML Schema and inter-dependencies between third-party software used within OGSA-DAI.
