I have a desktop that has a 4.5 Ghz 6-core processor, 16GB or RAM, and an SSD. It is dual-boot between Windows 10 and Ubuntu 14.04. It boot Windows 10 in ~8 to 10 seconds, while it takes Ubuntu over 3.5 minutes to boot. When I run
dmesg, I can see that a process called
sanitized_helpertakes almost 100 seconds to load (?). Then, Bluetooth: RFCOMM v.1.11 takes 110 seconds to load.
First of all, what is "sanitized_helper"? And concerning Bluetooth, Sure, I could disable Bluetooth on boot, but why does it take that long anyway?

EDIT: As Jeremy31 suggested, I booted into Windows 10 and shutdown with
shutdown -h and re-ran
dmesg. Ubuntu now boots in around a minute and a half, which is still a long time, but its progress! Here is the complete
dmesg output after shutting down in that way: http://paste.ubuntu.com/15344524/
Here are the contents of
