How fast is the full boot time of your operating system?

[SchumannFrequency]

This is the full boot time of the operating system in my case. BIOS checks, MBR and GRUB bootloader are not included in the measurement.

Software: Clear Linux and GNOME display manager (GDM)
Hardware: Intel 12600KF (stock) -- Kingston 6000 MHz CL40 -- GTX 650 1GB -- BIOSTAR B760MZ-E PRO -- Antec P6 -- Xilence XP550 -- ARCTIC i35 -- EVO 850 500GB

A suspicion is that it should score under 1 second if I plugged one of the fastest M.2 drives into the motherboard.

How fast does your operating system boot up when you do a full startup (= no hibernation or also no 'Turn on fast startup' enabled in the shutdown settings).

Windows reports a BIOS time of ~70 seconds, but I have a long BIOS check and I'm using OpenCore instead of Windows Boot Manager. Once OpenCore starts loading Windows (10) it takes about 5-7 seconds.

From button to password is about 15-20 seconds

The value I posted in the first post was not my fastest value, I sometimes score +- 0.07 second faster.
But it doesn't seem that the system can start faster than 1.4 second with the current configuration.

I may check to see what services start up, and if I disable the ones I don't use I may be able to get the system to start faster.
The three services that take the most time do seem like essential services to me, unless I can replace GDM with a faster login manager.

Or I can also just disable GDM and login with the terminal. Just to see what the impact on overall startup time is.

Aside from that, I see about seven services that may not be essential to me. If I tweak systemd for a few minutes I should score around 1.2xx (or 1.3xx) second.

Mine. Take in fact that I have 3 USB external HDDs

Reboo- what?

What is this thing you speak of and why would I need it?

I currently have only a single service disabled compared to the default configuration. The service is ModemManager.

But disabling this one service had a bigger impact than what I expected.

I know what you mean. But is it not a myth that Linux system never need a reboot?

Many Linux distributions ask a reboot after certain changes.
And rebooting Linux occasionally is necessary to ensure the system DOES boot if something unexpected happens.

I did extra investigation and the faster result was coincidence.
You need to mask many services before the systemd boot time gets faster.
