Can you suggest some tips and tricks for speed up Devuan?

deepforest · 2022-11-12 20:06:33

Without upgrading hardware;)

Please, post here if you have such tips and tricks.

Hi,

I disabled the spectre CPU-patches.
This is not recommend for e.g. cloud servers running potentially evil virtual machines. My computer is just a desktop.
The arguments are from https://make-linux-fast-again.com

# /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off tsx=on tsx_async_abort=off mitigations=off"
$ sudo update-grub

Head_on_a_Stick · 2022-11-13 13:29:03

Only mitigations=off is needed. I also do that :-)

Use this to check:

for i in /sys/devices/system/cpu/vulnerabilities/* ; do echo "$(basename $i): $(cat $i)" ; done

I would also recommend disabling all desktop trackers & miners, along with the display manager. And X, but that might just be me.

https://wiki.archlinux.org/title/Improving_performance is a good reference but not everything there will apply to Devuan, for obvious reasons. Devuan is already faster than vanilla Arch anyway

deepforest · 2022-11-13 18:09:57

Thanks All for replys)

Yes. As i know only mitigations=off in kernels upper 5.15.
So it works.

freeartist@devuan:~$ for i in /sys/devices/system/cpu/vulnerabilities/* ; do echo "$(basename $i): $(cat $i)" ; done
itlb_multihit: KVM: Mitigation: VMX disabled
l1tf: Mitigation: PTE Inversion; VMX: EPT disabled
mds: Vulnerable; SMT disabled
meltdown: Vulnerable
mmio_stale_data: Unknown: No mitigations
retbleed: Not affected
spec_store_bypass: Vulnerable
spectre_v1: Vulnerable: __user pointer sanitization and usercopy barriers only; no swapgs barriers
spectre_v2: Vulnerable, STIBP: disabled, PBRSB-eIBRS: Not affected

hey) Its very interesting question! On my second legacy PC i have 3 Linux)

1.Arch(vanilla)
2.Devuan Ceres
3.Artix(no systemd Arch)

The fasted for me is Artix, second is Devuan, third Arch

My second PC, legacy - c2d Q6600, gf9800gtx, 4gb ram

PS i want ask here? What Linux is better for

My first PC, modern - AMD r2600, radeon rx580, 32gb ram

I think may be vanilla Arch? I love play different games old and new)

That's an old Ryzen so I would expect Devuan to do well against Arch. Run the same games on both and compare framerates. CS:GO runs marginally faster under Arch for me (compared to Debian bullseye) but I have a 5th generation Ryzen.

Some desktop environments will slow the machine down noticeably. Cinnamon used to be particularly bad, although recently I think it's been more speed optimized. Using a minimal window manager such as DWM or Openbox or IceWM instead of a desktop environment can speed you up, especially on older equipment.

Using the latest version of an older generation LTS kernel instead of a new generation kernel will usually give you a speed boost according to years of benchmark tests on Phoronix website. LTS kernels such as the 5.10 kernel are optimized over a period of years, whereas newer kernels such as the various 6.x versions typically introduce regressions. If you aren't using brand new hardware that needs a new kernel feature then it's worthwhile to experiment with older LTS kernels. I have one machine that runs fantastic on the 4.9 kernel, and another that is very happy with the 4.19, and on most others I've been sticking with the 5.10 kernels lately.

Also it's worth checking the cpufreq scaling governor to see if it's in "powersave" or "performance" mode. I don't recall how Debian/Devuan normally set this. There's various how-to's online to check and to change this governor.

Building a kernel that's optimized for your particular equipment used to give about a 2%-3% performance boost (allegedly), although I don't think you'll see as much boost compared to the kernels that distros provide today. But it's always worth trying and worth learning about the kernel config options and how they might apply to your system. If you build your own optimized kernel, you'll probably "feel" like your system is running faster, even if it's not. And that's got to be worth something, right?

Lastly, in my personal experience, runit and s6 make systems noticeably faster in terms of booting and program start times compared to sysvinit and are especially faster compared to systemd. So on your Artix systems you'll have a lot of good options there. Also dinit seemed pretty zippy when I tried it.

And what you can say about MX Linux compare to Devuan? MX have lts kernel 5.10

choice is not rich https://nosystemd.org/ if we speak about Linux with "human face" and that working "out of the box"

GlennW · 2022-11-13 23:40:59

One thing I do, and check from time to time is services that load at boot.

rc-update, I turn off as many server services as possible...

ie, sudo, squid, openvpn, ssh, savecache, nethack-common, haveged, fancontrol (stops error spam), exim4, dictd, avahi-daemon and bluetooth.

Because I tether my phone as a modem, squid and openvpn are started after I connect to the phone long after the boot processes are done...

:-)

I thought that antiX with runit, Artix with s6, and a minimal Void installation were all shockingly fast. Anything with boot speeds of under a couple of seconds is startling to me, as I was an old time SuSE professional user in the days when we would count boot speeds in minutes. Rebooting used to be a good time to use the bathroom and get a coffee refill. With antiX, Artix, and Void, I'm too slow to even get out of my chair before I am being prompted to sign in again.

MX seemed pretty average to me - I don't recall ever being impressed with the boot speed or responsiveness with MX, but at the same time I wasn't disappointed. Seems like the last time I used it boot times were about 15-20 seconds. MX is loading a lot of services by default - I think GlennW is right that you want to go through and shut down unneeded services if you are trying to achieve boot speed. Also MX is using either sysvinit or systemd - the two slowest init systems that I've personally experienced.

Devuan is pretty fast, but not like antiX, Artix and Void in my experience. Once again, probably has to do with it using sysvinit and starting up more services by default than I really need.

andyprough Thanks a lot!

I thought that antiX with runit, Artix with s6, and a minimal Void installation were all shockingly fast.

But only Artix have xfce out from the box? Why antiX have no xfce by default? If i am install xfce on antiX its not broke the speed?

Also MX is using either sysvinit or systemd - the two slowest init systems that I've personally experienced.

Devuan is pretty fast, but not like antiX, Artix and Void in my experience. Once again, probably has to do with it using sysvinit and starting up more services by default than I really need.

This! So only one way to speed up Devuan is disable unneeded services?

Thanks! And how exactly turn off unneeded services technically? And what services is safe to disable? Were is i can get list of this services?

No. FPS is equal on all my systems. I am talking about booting, launching apps, responce time gui, and lag of DEs. How it can be measure? And its NOT subjective)

Give it time

And enjoy the massively outdated packages during the upcoming freeze. The Debian devs sometimes even leave critical bugs unfixed in the development branches until the release is done...

LoL. Devuan after hours working feeling like rubber. And Artix not it fast from the boot. On Arch when i push on "Application menu"(not Whisker) after boot, needed ~10-15! sec to it appear. On Artix all response is instantly.

antiX is ONLY window managers (Icewm, JWM, Fluxbox, Herbstluftwm) by default. I don't know if installing XFCE slows down the system - I have XFCE installed on antiX and the system seems plenty fast enough.

That and all the other stuff that everyone told you above. And anything else that we forgot to mention. I mean, it's Linux - there's like 100 different ways just to copy a file. There's basically an infinite number of combinations of settings and programs and desktops and configurations you could use with your distro, and each combination might give you different speed and responsiveness. So no, you could not say the "only" way to speed up Devuan is to disable unneeded services. It's probably one of the BEST ways to do it though.

Thanks again!) And what distros are you using and which one do you like the most?

So no, you could not say the "only" way to speed up Devuan is to disable unneeded services. It's probably one of the BEST ways to do it though.

Your case is different from mine. I almost never print anything, so I do not allow cups and cupsd to autostart, and I don't use bluetooth devices with the computer, so that's gone. I also don't use a graphical login manager, so your slim service would not be used on my system. And I find NetworkManager to be bloated, so I manage my network by other means. You just have to go through, familiarize yourself with the different services, and see what you need and what Devuan really needs. If you don't know what they are, you shouldn't be turning them off. Just asking other people's opinions isn't going to help you - you'll need to educate yourself.

GlennW · 2022-11-15 00:36:59

to get a list...

service --status-all

I use openrc init, so it may be different for you, but

show status...

rc-update

to edit a service's runlevel, to add, delete or modify the runlevel of each service

rc-update del ssh default
rc-update add ssh off

Be aware that service package updates may modify the runlevels, so you need to check periodically.

edit, couldn't locate this.
The old way was with chkconfig... but I can't find it anymore... but here's some info (link) about it.
