Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

I just ran some tests, with a clock timer and systemd-analyze. Here are the  
results.


No battery on laptop, only straight AC power outlet
systemd-analyze
Startup finished in 10.333s (kernel) + 26.091s (userspace) = 36.425s
My clock counts 58 seconds (including the time it takes for me to type the 2  
passwords)


Battery only at 8%, no AC power outlet in
systemd-analyze
Startup finished in 11.084s (kernel) + 26.310s (userspace) = 37.395s
My clock 59 seconds (again including the time it takes for me to type the  
passwords)



I swear I don't understand why it was giving me the time of 1 minute and some  
seconds before in systemd-analyze. Right now I get these consistent times in  
both systemd-analyze and real life time clock.
Well, in face of this, I would say that it's the best I will ever get without  
changing to an SSD. I will still try to disable some stuff, maybe it will get  
better or not, but I don't want services that are NOT needed running for  
nothing.


Thanks everyone anyway, I will let you guys know if something new comes up.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

I just ran systemd-analyze again and got this
Startup finished in 11.289s (kernel) + 30.593s (userspace) = 41.882s

Wtf?
The only thing I noticed different was that I was not running the laptop on  
battery but straight for the AC outlet. Does that even matter? I guess I will  
have to give it a few tests and see what is happening really.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

Would disabling some of those services prevent the booting of the system? As  
long as I can "systemctl disable / systemctl enable" I am okay with that.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

What would help then? Is there anything that can make the kernel load faster,  
or the only option is a)replacing the kernel b)buying SSD ?


Also, if you can offer some input to the questions I posed below, I would be  
very grateful (meaning the Ofono service and such).  Thanks.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[znavko]

I cannot know exactly cause I see names there for a first time now: gdomap,  
irqbalance, acpid, atd, setvtrgb, remote-fs-pre, nss-user-lookup.


You should have rescue usb flash to boot with it, to mount broken system
and reconfigure it.


disabling ofono, openvpn is ok. disabling avahi is ok too  
https://ccm.net/faq/739-disabling-the-avahi-daemon

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

Ok, so, running systemctl list-units I noticed some things:

ofono.service   loaded active running   oFono Mobile telephony stack
openvpn.service   loaded active exitedOpenVPN service
avahi-daemon.socket  loaded active running   Avahi mDNS/DNS-SD Stack Acti

As far as I am aware, I don't use Mobile phone in my computer, neither do I  
use VPN (I tried using BitMask but it leaks DNS, so for now I don't use it)  
and I think avahi is meant for using network printers which I don't have. So,  
it should be ok to disable these right?
I mean, it's not like these are in the critical chain MagicBanana mentioned,  
but I guess having less stuff running would not be bad either way, right? The  
thing is, am I considering it right? I couldn't find much information online  
about Ofono for example.
How can one know what each entry on the list-units option does? Which ones  
are essential and which ones are not?

Thanks.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[znavko]

you know I disabled tor service and tor@default service and my systemd says  
this:


# systemd-analyze
Startup finished in 13.233s (kernel) + 2.998s (userspace) = 16.231s

This means minus 16 seconds from userspace as in my previous post. Now I  
search how to move this and other services loading to later time after I see  
login page to speed up boot.


kernel loads very slowly 13 seconds is far from best. needs to learn which  
services are unnecessary like CUPS (printer), openvpn and so on from here  
`systemctl list-units`

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[znavko]

rfkill loads on boot and take a time. you can see it. needs to try to  
configure os with no soft blocking necessary interfaces and disabling rfkill.  
also networkmanager takes time on boot process. but there are faster  
alternatives I think. I was using wpa_supplicant and had much joy about it.  
but I found on trisquel distribution wpa_supplicant is not free. )) 

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

Thanks! Just noticed I had my updates disabled, so I decided to update my  
system. Who knows, maybe the kernel updates make it faster?

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

Thanks man. Yes, SSD would make huge difference, but I suspect there are  
things I can disable. I will have to try and discover how to disable certain  
items AND get them back up if I need to.

What did you mean about NetworkManager? Thanks.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[znavko]

I have ssd, Intel(R) Pentium(R) CPU  N3530  @ 2.16GHz, 4Gb RAM and I think my  
system boots fast. Faster then on Funtoo, Debian that I used before.


$ systemd-analyze
Startup finished in 13.248s (kernel) + 19.747s (userspace) = 32.995s

I think to disable unnecessary services, disable kernel modules such as  
bluetooth, ipv6.


SSD is a very important thing to speed up.

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

Yes it was directed at you... So the kernel is different... Too bad, can't  
make a proper comparison. But you almost make me want to change for Debian  
again, lol, that is a great boot time.
Guess I will wait for MagicBanana to reply, I am curious if everyone is  
having the same long boot process...

Re: [Trisquel-users] Speed up boot process of Trisquel 8

I assume the question is directed to me - I'm running and been running for  
over 3 yrs now Debian Stable.

Are you running Trisquel 8 with the standard installation kernel? Or another  
Linux-Libre flavour?

Re: [Trisquel-users] Speed up boot process of Trisquel 8

Ah ah ah. Tempting, but that still doesn't explain why my kernel takes 39  
seconds to boot (kernel alone). Though I would maybe think about getting an  
SSD later.
Are you using the standard Trisquel 8 kernel, or is it another Linux-Libre  
(maybe the one provided by jxself?).

Thanks.

Like I said to SuperTramp89, I don't understand why a default installation of  
Trisquel 8 takes so long, my hard drive is a 7200rpm one. Could it be because  
I have full disk encryption?

Other than that I would expect a T400 to boot faster...

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

That's what I consider really strange. Mine is a Librebooted T400, with a  
brand new fresh Trisquel 8 installation, with a 7200rpm hard drive.
I don't understand why it takes so long... You take 40 secs I take more than  
a minute.

Great stuff on all posts!

I run systemd-analyze blame and got this:

And a lot other stuff all under a second. I am wondering if any of these can  
be turned off and how to do it? I think I can get avahi off, and maybe  
apparmor? I don't have anything configured in apparmor, I only use firejail  
to restric programs (or maybe Trisquel has apparmor pre-configured??)

What is that ofono service?
Comparing to Geshmy I take a LOT of time to boot. Would like to get it under  
a minute at least :)


Thanks ahead for all the help guys

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[gnuser]

Thanks. I didn't know anything about that, I knew systemD was the default (I  
remember the heated discussions back then...) but I didn't know much about  
it. Those commands will allow me to make some analysis and hopefully some  
improvements (or at least make sure that over time stuff is not added up). I  
remember in another installation I also had services starting up (like Tor  
and I2P) which I didn't use all that much and wanted to just start them  
manually but they were taking time at boot.

I will report back if I find anything interesting :)

Thanks!

Re: [Trisquel-users] Speed up boot process of Trisquel 8

[g . smyli]

I believe systemd is installed by default.

Here are a couple of commands with example responses from my laptop running  
Trisquel 8:


rally@silverbird:~/Desktop$ systemd-analyze
Startup finished in 7.907s (kernel) + 25.403s (userspace) = 33.311s

rally@silverbird:~/Desktop$ systemd-analyze blame
  7.601s NetworkManager-wait-online.service
  6.136s dev-sda4.device
  5.032s apparmor.service
  3.711s NetworkManager.service
  3.294s postfix.service
  3.257s accounts-daemon.service
  2.894s lightdm.service
  2.645s networking.service
  2.441s console-setup.service
  1.909s rsyslog.service
  1.868s polkitd.service
  1.832s grub-common.service
  1.587s systemd-fsck@dev-sr0.service
  1.549s rc-local.service
  1.299s keyboard-setup.service
  1.146s irqbalance.service
  1.038s systemd-journald.service
.and lots of other suff taking less and less time to get started.

I noticed tor.service was starting at boot and I haven't been using it so I  
did...


rally@silverbird:~/Desktop$ systemctl status tor.service
rally@silverbird:~/Desktop$ sudo systemctl stop tor.service
rally@silverbird:~/Desktop$ sudo systemctl disable tor.service

rally@silverbird:~/Desktop$ systemctl | grep service
will also give a list of services starting up (configured in the /etc/rc.  
files)


All the services that start on mine seem necessary. 33 seconds isn't to bad  
but if my laptop booted faster that would be nice. The /etc/rc. files allow  
for changing the order in which different things boot. Tor had a problem  
because I don't hook up to the internet by default and it was trying to.


I know there is a lot more one can do with systemd and systemctl. I'm no  
expert.
