Optimizing Network Performance: Benchmarking of NVIDIA Bluefield-2 Offloading Capabilities

The growing demand for higher Internet speeds is placing significant strain on general-purpose processors, particularly in handling network processing tasks. This trend has driven the shift toward the offloading of such tasks to specialized hardware. SmartNICs alleviate CPU load by efficiently managing network processing while providing programmability and customization. However, mastering the deployment and utilization of SmartNICs poses a significant challenge due to the steep learning curve involved. In this study, we test and evaluate the performance of NVIDIA’s Bluefield-2 SmartNIC under a range of conditions, with the objective of achieving 100Gbps throughput on a single server. Our results demonstrate that specific libraries can enhance the processing of common traffic types, such as TCP and UDP, by up to tenfold, thereby enabling the system to reach 100Gbps line rate.
