slow boot XPS 13 9370 Windows

Hi,

I got my new Dell XPS 13 9370 just a few days ago. After rebooting it a few times I was wondering if it is normal that the startup takes up to 30 seconds equipped with a M2 SSD? I just want to add that I have already uninstalled the annoying McAfee and disabled and enabled fastboot a few times but the Bios time still remains between 10-20 seconds and the whole startup process is not faster than 20-30 seconds.

...I know I am "complaining on a high comfort level" but I am just expecting a fast startup considering the hardware...

Thank you in advance for sharing your experience
