+cgroup v2 is the current version of the Linux cgroup API. cgroup v2 offers several improvements over cgroup v1, including a unified hierarchy, safer sub-tree delegation, new features such as link:https://www.kernel.org/doc/html/latest/accounting/psi.html[Pressure Stall Information], and enhanced resource management and isolation. However, cgroup v2 has different CPU, memory, and I/O management characteristics than cgroup v1. Therefore, some workloads might experience slight differences in memory or CPU usage on clusters that run cgroup v2.
 
 You can change between cgroup v1 and cgroup v2, as needed. Enabling cgroup v1 in {product-title} disables all cgroup v2 controllers and hierarchies in your cluster.
