Grid is a highly distributed heterogeneous environment which interoperates towards completing a common goal. As such, grids performance is highly dependant on the speed of data transfer between systems of which grid consists. Most commonly used and a "de facto" standard for data transfer on grid systems is GridFTP [7]. While working on CRO-GRID Infrastructure [3] project, we faced problems with small data transfer speeds when transferring small files. In this paper we present a program we have developed which uses GridFTP and speeds up data transfer of large number of small or medium sized files. We also present empirical results of the performance measurements achieved while using the implemented system.
