Subject: Re: PATCH] cpuidle: A new variant of the menu governor to boost IO performance
Date: Fri, 11 Sep 2009 23:03:09 +0100 [thread overview]
Message-ID: <20090911220309.GB30989@srcf.ucam.org> (raw)
In-Reply-To: <20090911174019.1ed02737@infradead.org>
When you say that a bit more power was used, is that instantaneous power
draw or total power consumption over the run of the benchmark? I'd have
expected that completing it 50% faster and then going idle would be a
win overall.
