On my laptop with this CPU:
model name : Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz
I am using the ondemand governor:
$ cat /sys/devices/system/cpu/c*/cpufreq/scaling_governor
ondemand
ondemand
ondemand
ondemand
and the system is very slow to answer some inputs:
- the text output pauses for several seconds while I am typing this text
- trying to scroll a firefox window takes several seconds
- switching tabs in firefox takes several seconds
- ...
Setting the governor to "performance" fixes this problem.
Note that this bug does not reveal itself immediately after boot. It takes a suspend/resume to show up.
