positive.code: 
  Examples of kernel arguments you could set include:
  
  * **selinux=0**: Disables Security Enhanced Linux (SELinux).
  While not recommended for production, disabling SELinux can
  improve performance by 2% - 3%.
  
  * **nosmt**: Disables symmetric multithreading (SMT) in the kernel.
  Multithreading allows multiple logical threads for each CPU.
