Hmm, I must have missed the distinction between the two you have mentioned. Correct me if I am wrong but "latency sensitive" workload is the one that cannot use the high limit, right. For some reason I thought that your pro-active reclaim usecase is also not compatible with the throttling imposed by the high limit. Hence my conclusion above. -- Michal Hocko SUSE Labs
