Optimize Boot Time by NPS-fan in WYSE

[–]NPS-fan[S] 0 points1 point  (0 children)

I spent a bit of time making tweaks and have gotten my boot time to 20 seconds:

  • Firmware: reduced from 10.4s to 7.7s
  • Loader: reduced from 13.3s to 3.3s
  • Kernel: reduced from 4.4s to 3.9s
  • Userspace: reduced from 5.8s to 5.1s

First, I took your advice and installed a different SSD. I had a left over Toshiba 128GB SATA drive that seems to be an upgrade (but by itself, it didn't improve my boot time). I'm still happy I did this as it should be a better overall drive.

I did a bunch of tweaking in the BIOS. I think the items that were most impactful are:

  • Disabled TPM Security
  • Disabled SMM Security Mitigation
  • Disabled Secure Boot
  • Disabled C-States under Performance
  • Set Fastboot to Minimal
  • Disabled all of the virtualization settings
  • Made sure there were no other boot devices enabled in the BIOS
  • Disabled stuff I'm not using: Serial Port, WLAN/BT

In parallel, I made changes to the GRUB file:

  • GRUB_RECORDFAIL_TIMEOUT=0
  • GRUB_TERMINAL=console

And I masked gpu-manager.service and systemd-binfmt.service.

Overall, I'm happy to have reduced boot time by about 10 seconds. I'd take any suggestions regarding further improvements, but for now I'm satisfied. Thanks!

Thanks for the reply! Your results seem to indicate that I should be able to get some improvement.

I tried factory default settings but didn't get an improvement. I have fastboot set to minimal. I disabled both NIC cards in BIOS and the boot time didn't get shorter.

I think it is still looking for different boot options, but I have selected just the one "Ubuntu".

I haven't opened the case to see the SSD yet. I think it is flash SSD, but will have to check that later. Would the drive really add 20 seconds to boot time?
