KCD Helsinki 2026 Talk For more information about KCD Helsinki and Kubernetes Meetups in Helsinki follow us in LinkedIn:   / kcd-helsinki   Antti Kervinen and Feruzjon Muyassarov: Optimizing a Node for Low Latency and Real Time Workloads This talk gives an overview of what (all) really makes a difference for latency sensitive workloads. That is, how to get predictable execution and low latency responses from critical services and real-time containers. You will learn about partitioning Kubernetes node resources, classifying workloads, tuning resource partitions and tuning containers for each of them. You will get ready-to-use recipes to try with your own containers, without modifying their images. In addition to a walk through of established technology like isolated CPUs, memory and device locality, and cache and memory bandwidth allocation, this talk covers in more detail very recent enhancements in container runtimes and their effects. For instance, combining two new features, container-specific Linux scheduler and CPU power saving state controls, one can reduce processes’ wake-up latency even by 99 % in some occasions.
