All,

I have been using hrt patches to minimize wakeups and increase avg C4
residency time. With an idle system I can manage to get > 99% in C4 with
avg residency time of 120ms with 7-8 wakeup/s. This requires
1) disabling many essential services in gnome
2) disabling DRI (I can't live without compiz ;-))

However, when certain essential gnome services and DRI are not turned
off, I get 16-20 wakeups/s with > 95-99% in C4 with avg residency time
of 30-50ms is.

Could somebody please tell me if going from the former described
configuration to the later wastes too much power ? Assuming that one
needs a usable system, what is a good range for the following parameters
and which ones are more important than the other

1) wakeups/s
2) avg residency time in C4
3) %age of time spent in C4

Thanks

Ganesha
