Speed up boot time

Hello, I noticed slow boot time on my system. I have SSD Plextor 128 GB M.2 2280 SATA III (PX-128S3G) and find it very slow comparing to old SSD 2,5’’ I have on another laptop. My main laptop is Dell Inspiron 7577, 16 GB RAM. I use Ubuntu and Elementary OS before and system boot was even slower. I don’t now is that SSD is so slow or the reason is I have also second disc HDD for /home?
I want to speed up my boot time and remove some unnecessary services. Can somebody tell me what services I can disable?

What happen if you mask the service ?

~$ sudo systemctl mask systemd-networkd-wait-online

Wait for @ricklinux he is the better one for masking

Thanks, nothing happen, my network works fine :slight_smile: Can I mask also NetworkManager-wait-online.service?

I have also problem with mounting my home shares. I’m in work now with my laptop and system try to mount my home nfs shares. I have error on boot: FAILED mount nfs mnt-nas.mount and when I shutdown my laptop I see FAILED unmount /home and /tmp.

You can also mask to → sudo systemctl mask NetworkManager-wait-online.service

Since you have NetworkManager enabled, the former is not necessary.


Thanks. Can I mask any other services? Can I make something with my nfs share. For example to auto mount only on weekends when I bring my laptop home?

It has already lowered the boot time by more than 13 seconds, so its boot remains at normal values.

At your own risk you can touch and see, but I don’t think it necessary, in my opinion.

Hi, I have now similar output.
systemd-analyze Startup finished in 2.108s (kernel) + 5.711s (userspace) = 7.819s graphical.target reached after 5.710s in userspace
so it’s nice but do I have to worry about that info at the shutdown: Failed to unmount /home?

I don’t think so, it will change in next updates, as long as it keeps rebooting and powering up smoothly, don’t worry.

OK, thanks for help.
