Dear Linux folks,
According to `systemd-analyze` the UEFI firmware on several systems, for example the laptop Dell Latitude E7250 and the desktop board MSI B350M MORTAR, take over ten seconds to initialize.
$ systemd-analyze Startup finished in 11.193s (firmware) + 1.558s (loader) + 4.155s (kernel) + 2.007s (userspace) = 18.914s graphical.target reached after 1.983s in userspace
Talking to other people, I heard, Microsoft Windows since version 8 can activate some fast/quick boot mode in the firmware.
I haven’t even found the specification for that mode. It could be something like [1], but I do not think it is:
> Fast Boot is a feature in BIOS that reduces your computer boot time. If > Fast Boot is enabled: > > • Boot from Network, Optical, and Removable Devices are disabled. > • Video and USB devices (keyboard, mouse, drives) won't be available > until the operating system loads.
Some other sources [2] say, that MS Windows just uses hibernation to boot quicker, but I do not think this is it, because with hibernation there should be also a ten seconds delay, right?
Do you know more about this mode, and how it works? Could it be implemented for Linux?
Kind regards,
Paul
