Nix daemon process CPU scheduling policy. This policy propagates to build processes. other is the default scheduling policy for regular tasks. The batch policy is similar to other, but optimised for non-interactive tasks. idle is for extremely low-priority tasks that should only be run when no other task requires CPU time.
Please note that while using the idle policy may greatly improve responsiveness of a system performing expensive builds, it may also slow down and potentially starve crucial configuration updates during load.
idle may therefore be a sensible policy for systems that experience only intermittent phases of high CPU load, such as desktop or portable computers used interactively. Other systems should use the other or batch policy instead.
For more fine-grained resource control, please refer to systemd.resource-control(5) and adjust systemd.services.nix-daemon directly.
