For performance and deterministic purposes, we need to define Musique interpreter instance as important for operating system.

Linux

nice value can be set, but only on processes with CAP_SYS_NICE capability which can be aquired either by running as root or marking executable with this capability:

$ sudo setcap cap_sys_nice=ep executable

Unfortunately this is not a part of ELF file, so it must be applied manually.

Lower value of nice (negative) means more scheduling privilages.

macOS

Nice and root required as in Linux but without capabilities found on Linux
