Tracking priority in that way would almost certainly be an expensive thing to do. Nowadays, control groups can contain that backup job pretty nicely.

- skyde 6y agoCould you explain how CGroup would prevent page-fault causing more disk IO than allocated to the Control group ? On most LINUX distro I have seen, running a process that allocate too much memory just freeze the whole use interface. 1- mouse cursor move super slowly 2- it become almost impossible to drag window and close windows ... If what you are saying it true, simply running critical process (mouse driver, X-Windows, Gnome) in a high priority Cgroup would solve this problem.
