APIC and Preemptive mode in Linux Kernel 2.6.5-1.315 ?

[Ernest L. Williams Jr.]

Hi,

Are APIC and PREEMPTIVE MODE turned off for the kernel in FC2T2?

If so, what is the performance impact with APIC off in dual processor
box?

Also, what about preemptive mode?

I guess a more general question is:
Where is the reference on what features Fedora turns on in the kernel?

 

Thanks,
