Re: Re: Changes for 4.0-RC2

Unless there is a good reason for doing so, I disagree with disabling NoHz by default.  This was implemented after being brought up on this email list in early March 2009.  NoHz has multiple benefits, including much-improved performance in a VM and lower power consumption.

The last couple paragraphs of this CNET article note some of the benefits of CONFIG_NO_HZ (tickless kernel).
