Re: [PATCH] x86: Reduce the default HZ value

[Christoph Lameter]

I think we need to reduce the general tick frequency to be as low as
possible. With high resolution timers the tick frequency is just the
frequency with which the timer interrupt disturbs a running application.

Are there any benefits remaining from frequent timer interrupts? I would
think that 60 HZ would be sufficient.

It would be good if the kernel would be truly tickless. Scheduler events
would be driven by the scheduling intervals and not the invokations of the
scheduler softirq.
