My computer has a Asus x99 E WS mobo, with intel i7-6850K processor and ubuntu 14.04 installed on a SSD. Yet the boot time is more than 30s which seems too high for such a powerful machine.

Running bootchart (image here) shows that the system is idle for the first 10 seconds(except for some kworkers). How do I fix this?

EDIT: This machine has 4 GPUs, does it have anything to do with the slow boot time?

  • 30 seconds for a boot 14.04 is actually rather good. Boot time has been greatly improved in subsequent versions, tough (at least in my experience with a Dell with SSD and Nvidia). Try to install 16.04; it will probably get much better. Remember that, on 16.04, [bootchart will be deprecated](http://askubuntu.com/a/788886/29595). – dadexix86 Oct 20 '16 at 07:10
  • And no process uses the CPU, or the disk, apparently. – Jos Oct 20 '16 at 07:11
  • @dadexix86 I tried 16.04 too, I am facing the same problem. I have another machine running 14.04 which is pretty fast (~ 14s, lower specs). – StarLord Oct 20 '16 at 07:16
  • How much RAM do you have? – dadexix86 Oct 20 '16 at 08:27
  • @dadexix86 32GB – StarLord Oct 20 '16 at 08:36
  • So it's not a problem of RAM. But with 16.04 you have the same problem? That's weird, because `init` should not be there anymore :S Is it not that you started with `upstart` when you tried? – dadexix86 Oct 20 '16 at 09:11
