Episode 52 of The Linux Podcast digs into Control Groups v2, the kernel feature quietly reshaping how containers use CPU and memory. Lucas and Luna break down the specific change that made Cgroups v2 production-ready in 2024 and 2025: the unified hierarchy. They walk through a real example from Meta's 2024 paper showing a 12% reduction in CPU tail latency after migrating to Cgroups v2, and explain why the old v1 hierarchy led to resource fights between systemd and Docker. The episode covers the practical migration path, the one kernel parameter that catches everyone off guard, and why Cgroups v2 is now the default in every major distro from Fedora 37 onward. No fluff, just the mechanics that keep Linux containers stable under pressure.
