Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) BIOS, Kernel & System Settings o Identified: A few BIOS settings affecting throughput/latency More than 20 system-level settings affecting throughput/latency and overall system performance and scalability 1 change to Kernel settings which affects throughput o Each setting was benchmarked to have a thorough understanding of its impact o Finally, have a best-known configuration for both forwarding and end-point scenarios 12
Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Configuration of BIOS / P-States Feature Orig. Status New Status Justification Hyper- Threading Enabled Disabled Will impact IRQ affinity settings Turbo Boost Enabled Disabled Unstable performance results, higher jitter C-States Enabled Disabled Prevent CPUs from sleeping; causes higher latency P-States Enabled Disabled Run at maximum frequency & voltage at all times These settings may affect other system characteristics (i.e. power utilisation) 13
