Suggestion: increase the VM dirty writeback time from 5,00 to 15
seconds with:
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
This wakes the disk up less frequenty for background VM activity
Suggestion: enable the noatime filesystem option by executing the
following command:
mount -o remount,noatime / or by pressing the T key
noatime disables persistent access time of file accesses, which
causes lots of disk IO.
Suggestion: Enable the ondemand cpu speed governor for all
processors via:
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Suggestion: Disable 'hal' from polling your cdrom with:
hal-disable-polling --device /dev/cdrom 'hal' is the component that
auto-opens a
window if you plug in a CD but disables SATA power saving from
kicking in.
Suggestion: Enable the CONFIG_HPET_TIMER kernel configuration option.
Without HPET support the kernel needs to wake up every 20
milliseconds for
some housekeeping tasks.
Suggestion: Enable the CONFIG_ACPI_BATTERY kernel configuration
option.
This option is required to get power estimages from PowerTOP
Suggestion: Enable the CONFIG_USB_SUSPEND kernel configuration
option.
This option will automatically disable UHCI USB when not in use,
and may
save approximately 1 Watt of power.
