Ok, perhaps you don't have the tools to measure the load, so I won't ask
you to do it, but ...
Have you ever compared temperature and battery life when switching
between ondemand and performance?
How much is the difference on your machine?
There's a big difference in terms of heat. Running my laptop on
performance shoots the temperature up to 80c and higher whereas ondemand
keeps it 45-80 (80 when ondemand decides it needs to go full throttle).
Keeping in on performance heats up the laptop to a point where its
uncomfortable to rest the palms on it. I most certainly do not want to
see the kernel selecting performance as the default choice.
Havent tested with battery but I suspect, the battery will run out
faster when its on performance as opposed to ondemand if not for
anything else, to power the cooling fans.
