Abstract: OGSA-DAI provides an extensible Web service-based framework that allows data resources to be incorporated into Grid fabrics. The current OGSA-DAI release (OGSA-DAI WSI/WSRF v2.2) has implemented a set of optimizations identified through the examination of common OGSA-DAI use patterns. In this paper we describe these patterns and detail the optimizations that have been made for the current release based on the profiles obtained. These optimizations include improvements to the performance of various data format conversion routines, the introduction of more compact data delivery formats, and the adoption of SOAP with attachments for data delivery. We quantify the performance improvements in comparison to the previous OGSA-DAI release.
