Low latency tuning guide
This guide describes how to tune your AMD64/x86_64 hardware and Linux system for running real-time or low latency workloads. Example workloads where this type of tuning would be appropriate: Line rate packet capture Line rate deep packet inspection (DPI) Applications using kernel-bypass networking Accurate benchmarking of CPU bound programs The term latency in this context refers to the time betwe
