Phoronix: Linux 3.15 Should Suspend & Resume Much Faster

The Linux 3.15 kernel will feature a large number of ACPI and power management updates when its merge window opens in the days ahead...

it saved 80% time in resume_noirq phase

The key question is how much % time resume_noirq takes compared to resume as a whole.

Man ,we're talking about seconds, sometime even less than two seconds to complete standby and resume.
Nothing too exciting, but still nice.

It will be available on next linux distros by default?

[Viper_Scull]

On my system, Arch Linux + SSD suspend takes less than 1 second.

I felt like suspend and resume were already pretty fast. The only thing that could speed up is KDE plasma resuming. Even then I feel like it's already quick enough.

It's funny to read ACPI enhancements in the next kernel release, when Ubuntu wants to ditch ACPI from it's universe

The kernel maintainers did not want to implement it in the first place, but there isn't much choice, now is there.

I wish if they could somehow improve boot speed. It is probably not kernel fault. Boot speed of popular Linux distributions is horrible compared to Windows 8. It gives a bad impression of bloated and slow system to new users.

That's because Windows 8 doesn't really do full boot/shutdown cycle. When you press the shutdown button, the system goes into hybrid hibernation, and booting into it just thaws it out, that's why it seems so fast. You can have similar speed on linux by simply hibernating (if by any chance it works for you).
