Hello

I compile myself the preempt kernel usually.

For the preemptible kernel, I was aware of the "preemptible kernel" and "timer frequency = 1000Hz" options; 

Could please tell for the @ other otptions:
    - for the cgroups disabled: is it the "General Setup -> Control Group Support" set to 'no'?
    - for the "no tics" options disabled, is is the "Processor Type and Features -> High Resolution Timer Support" set to 'no'? If not, what is the option to be disabled?
