Change cpu process priority
npm install renice
const renice = require('renice')
// pid, priority
renice(process.pid, 42)
.then(() => {}).catch((err) => {})
For more informations about priorities see https://nodejs.org/api/os.html#os_os_setpriority_pid_priority. Note that on old node versions we'll fallback to wmic on windows and renice on unix.
