We would like to propose switching the default OCI container runtime in CRI-O to crun. crun has been a GA project for a while and is written in C, offering better performance than runc. Its efficiency in terms of faster container start times and lower memory usage makes it a more optimized runtime for modern workloads.

crun provides better support for WebAssembly (WASM) workloads, tighter Systemd integration for resource management, and enhanced security through improved cgroup and namespace handling.
