asubedi, thank you for reporting this and helping make Ubuntu better. Gutsy
Gibbon reached EOL on April 18th, 2009.
Please see this document for currently supported Ubuntu releases:

We were wondering if this is still an issue on a supported release? If
so, can
Confirming on lucid LTS 2.6.32-27-generic-pae #49-Ubuntu SMP Thu Dec 2

I only found out about this problem (default setting ondemand) after enabling
CPU freqency monitoring while exploring my system.
Behavior should be such that if a SINGLE thread uses 90 %
I can confirm essentially the same behavior on my laptop (Intel Atom
N270 @ 1.66GHz) running Jaunty 9.04

I can confirm this on a laptop AMD Turion X2 RM-70, Intrepid AMD64.
At first I was mesmerized to find Avidemux running 4 times faster in
Vista than in Ubuntu on the same machine. Then I realized it was not
using all its cpu power, so I changed the cpufreq governor to
'Performance' and it worked
I did have the same problem as unggnu. For example just using firefox
would never change the cpu frequency from the lowest 1GHz (on a AMD
6000+ with a maximum frequency of 3GHz ). I was playing around with the
settings and my on_demand scaling seams to be working as it should after
I did the
We need an option in gnome-power-manager to enable the performance
governor in Ubuntu 8.10. The ondemand governor does not work properly
for everyone. On my Thinkpad T42, flash video playback at fullscreen is
choppy. The cpu will go to max, but not fast enough to prevent choppy
playback. The T42
This is still an issue in Intrepid. I have a quad core q6600 and it seems that
the ondemand governor uses the highest frequency very rarely.
If I set one core under 100% load e.g. with cpuburn ondemand doesn't scale up.
Most of the times it even doesn't scale up if two cores are under 100% load
that's not a gnome-applets issue

ondemand governor does not use maximum frequency under load
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:
1) If you are comfortable

I've done more testing and found that what I've been experiencing may or
may not be replicating this bug. I was loading the processor using
Prime95 (available at http://www.mersenne.org/freesoft.htm) to test each
core under load. The reasons the ondemand cpu frequency governor was not
ramping up
Regressed to New because I am unsure if I successfully confirmed the
original submitter's bug.
