Since "Container-aware GOMAXPROCS" was introduced in golang version 1.25.0, there are new paths accessed on every go runtime startup. Release notes: https://tip.golang.org/doc/go1.25#container-aware-gomaxprocs > At startup (defaultGOMAXPROCSInit), we read /proc/self/cgroup and > /proc/self/mountinfo to find our current CPU cgroup and open its > limit file(s), which remain open for the entire process lifetime. We > periodically read the current limit by rereading the limit file(s) > from the beginning. > > https://github.com/golang/go/blob/go1.25.0/src/runtime/cgroup_linux.go#L13
