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. Commented Apr 8, 2017 at 12:45
  • does that mean, for this configuration ~50 sec is optimum boot time?

  • Looks normal, boot-time varies, sometime file-systems are checked during boot, sometime not.

  • 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. Commented Apr 8, 2017 at 12:51
  • In terminal type sudo fdisk -l and see if it tells you that any of your disk partitions are misaligned.

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:

  • Don't forget to remove unnecessary services and startup applications. Commented Apr 8, 2017 at 16:17
  • taken care of unnecessary services and startup applications.
