This paper evaluates the performance of the emerging OGF standard OGSA - Basic Execution Service (BES) on three fundamentally different Grid middleware platforms: UNICORE 5/6, Globus Toolkit 4 and gLite. The particular focus within this paper is on the OGSA-BES implementation of UNICORE 6. A comparison is made with baseline measurements, for UNICORE 6 and Globus Toolkit 4, using the legacy job submission interfaces. Our results show that the BES components are comparable in performance to existing legacy interfaces. We also have a strong indication that other factors, attributable to the supporting infrastructure, have a bigger impact on performance than BES components.
