Let's say I want to prioritize a few processes that are running on a device with high memory pressure. These processes are UI processes (Android, specifically) and are running very slowly in this state. When I grep for my process in
ps -eo min_flt,maj_flt,cmd
I can see that my major page faults are very high (thousands for a UI actions like opening a new Android activity).
If renice my processes to a lower niceness (higher priority), can I expect to see less maj page faults? Increasing priority should give it more CPU resources, but I'm not sure if that will speed up the process if the bottleneck is memory pressure/page faults.
