But, my purpose is isolate workload between applications and guarantee stable performance/latency and memory controller's limiting page usage feature will do half of work. So, per-cgroup page-cache control is (maybe) good enough for making applications stable by keeping room for immediate use of anon and by avoiding unnecessary swapout. but above can be archieved by - reserve/guarantee amount of free memory by some technique, bacground kthread, throttling, - do good design of swappiness. - etc... So, the word "limiting page cache" itself is not important. Above will limit amount of page-cache as a result. Ways to reach my goal is not one, maybe. I should find the best one :) Thanks, -Kame _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
