Ok, perhaps I jumped the gun
Although there's a rouge AV with that process name. Just FYI, Unthreat is the most CPU-hungry process in your boot sequence, although this is typical for anti-virus software.
I don't see anomalies in the provided log, but one thing stands out.
You've got a 15 second period that starts at around 18th second during which the CPU activity is present, but disk activity isn't. The process that consumes CPU is System (4), and its child process is smss.exe. I can't say what exactly goes on, but I assume it's either PreSMSS or SMSSInit boot phase during which drivers are loaded.
Perhaps, you've got a bad driver update, and I'd especially look at videocard drivers that frequently cause delays during these two phases. Another indicator of hardware/driver issue is your your statement:
Today my BIOS time is 23 secs
Taken at the face value, it means BIOS is having troubles with initializing hardware.
If this just happened today, System Restore to the earlier point is a good start. The next step would be to explore driver versions, especially video.
If you're still not happy with boot time, use the
clean boot technique to disable the third party software and services and see if it improves the situation. If so, restore third party stuff one by one or in small groups until you're back to the issue. That's how you'll know what the culprit is.
