Using strace, I discovered many programs are constantly busy these days. No wonder one can't seem to save power. There ought to be a law... ===== Subject: Re: silent PC vs. emacs Newsgroup: gmane.emacs.pretest.bugs From: Dan Nicolaescu <[EMAIL PROTECTED]>
...The OLPC/Fedora people are working on eliminating application wakeups in order to save power. I cite here from one of the bug reports about this: "We're working with RH engineers on a tickless idle kernel, which has the goal of reducing power and hypervisor loads when the system is idle. This is done by removing the regular ticking clock when the system is idle, so that in theory long sleep periods are possible for the hardware (or hypervisor). The kernel portion of this works great, however when using a gnome desktop there are many however when using a gnome desktop there are many timers going off all the time for userspace, so many that the actual savings are not so great (about 250 events per second)." Given that so many applications wake up so often, what emacs does might not be measurable at this point, but it might make a difference in the future.
