Quality attribute CAN-2.j (Performance) states, “The combination of transfer efficiency and impact of failures and restarts provides efficiency that is at least as good as 50% of peak theoretically possible throughput of optimal network path and storage systems.” In practice, all of the network and local storage connections that XSEDE provides are shared by many users, which means that each user only receives a portion of the total network and storage connectivity capacity. To satisfy this quality attribute, XSEDE would need to also provide a mechanism for reserving network and local storage connections for single use (e.g., for a file transfer request).
