Performance Evaluation

In this section, we analyze the performance of the cryptographic framework. We have ran a series of micro-benchmarks that allowed us to determine the limits of the framework and potential directions for improvement. We use the OCF for simple cryptographic tasks, comparing different cryptographic accelerators with the case of pure-software encryption, and provide a cost break-down. We also attempt to quantify the benefits to be had by the system at large, when off-loading cryptographic operations to hardware accelerators. Finally, we evaluate the load-balancing feature of OCF, by simultaneously using multiple accelerators on the same machine.
