I have recently purchased a new lenovo thinkpad e470, which packs 8GB of RAM, 1TB of hard disk and an intel i5 7th gen processor.

I was expecting a optimum boot load time with this system configuration, but its taking 40sec to show login screen and 10sec to show applications after login.

I have referred many related questions and these are all different logs I got from my system.

I installed ubuntu by selecting 'Erase and install ubuntu' option.

dmesg output here.

And my /etc/fstab file is as bellow.

I have also modified below files to give a try

  • /etc/default/grub modified GRUB_TIMEOUT=10 to GRUB_TIMEOUT=3
  • /etc/systemd/system.conf modified DefaultTimeoutStartSec=10s DefaultTimeoutStopSec=10s

Still I am not able to get any boot load time improvements. Can anyone suggest me how to improve boot load?

  • It doesn't look like anything is out of the ordinary. 50 seconds may not be a speed record, but it's also not catastrophic. Fast or slow is very subjective, and sometimes, the only way to get optimal boot times is to adjust one's own expectations. – mikewhatever Apr 8 '17 at 12:45
  • does that mean, for this configuration ~50 sec is optimum boot time? – Aparichith Apr 8 '17 at 12:47
  • Looks normal, boot-time varies, sometime file-systems are checked during boot, sometime not. – mook765 Apr 8 '17 at 12:50
  • IMHO, yes, it's quite alright for a PC with an HDD of probably 5400 rpm. Had there been an SSD, I would have expected faster boot times. It is not uncommon these days to put the OS on an SSD, and use an HDD for data. – mikewhatever Apr 8 '17 at 12:51
  • In terminal type sudo fdisk -l and see if it tells you that any of your disk partitions are misaligned. – heynnema Apr 8 '17 at 15:09

My computer is 7 years old Lenovo G560 Intel i5, 8gb ram, 120 gb Samsung SSD disk. SSD is connected to old Sata 2 interface. Write speed is about 100 MB/s. I'm using XUbuntu 16 and boot speed is about 15 seconds, shutdown speed is about 5 seconds. If you use SSD disk your boot time will decrease.

And I'm using /tmp folder in RAM. Add this line to /etc/fstab and restart your system then your boot and shutdown times must be decrease.

tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev,exec,mode=1777,size=1024M 0 0

And this site may help some issues about that how to tweak ubuntu:

  • didn't improved any boot time! Thanks for the links. – Aparichith Apr 8 '17 at 15:38
  • Don't forget to remove unnecessary services and startup applications. – kodmanyagha Apr 8 '17 at 16:17
  • taken care of unnecessary services and startup applications. – Aparichith Apr 8 '17 at 16:28
