One possible way would be to run this find/du workload inside a memory cgroup with high limit set to something reasonable (that will likely require some tuning). I am not 100% sure that will behave for metadata mostly workload without almost any pagecache to reclaim so it might turn out this will result in other issues. But it is definitely worth trying. -- Michal Hocko SUSE Labs
