Hello Tarmo,
you were right I just disabled the snap package and I earned 22 sec, thanks

At the same time, I've realized that I don't need such a modern kernel, so
I decided to test with a more "stable" one.

But as you can see the problem is still present, the userspace boot time
takes too much time.
so if it's not the kernel version ... how can I do better times?
