You keep bringing this up without an actual analysis of a wider range of workloads that would prove that the default behavior is really suboptimal. You are making some assumptions based on a very specific DB workload which might benefit from a more aggressive background workload. If you really want to sell any changes to auto tuning then you really need to come up with more workloads and an actual theory why an early and more aggressive reclaim pays off. -- Michal Hocko SUSE Labs
