Not doing anything special, just running

systemd-analyze timeit's most likely that "firmware" and "loader" are to do with UEFI (Unified Extensible Firmware Interface) and the bootloader files loaded by it .. so don't show up on non-uefi systems.

Which is still a pretty quick boot time no matter how you look at it :)

For my little Dell D430 with an SSD and Peppermint Seven I cannot complain:

Code: [Select]
xyz@abc ~ $ systemd-analyze time
Startup finished in 4.164s (kernel) + 10.044s (userspace) = 14.208s
;D 8)

I hadn't checked the little Dell yet :)

I do however know it boots faster than my A10 quad core lappy that also has 4 times the RAM ???

Heh !  Every community is different ... 

Assuming we're all in concordance, that  'systemd-analyze time' is the best way to go, may I suggest some visual confirmation for skeptics ?!?!?

Code: [Select]
╭─vindsl@Boogaloo-5 ~ 
╰─➤  systemd-analyze plot > ~/Desktop/`date "+%d-%b-%y-%T"`-plot.svg

Anyone can doctor a text file -- haxoring a .svg file, not so easy.   ;)

This looks very similar to the old '/sbin/init' version of Bootchart, and is probably easier for noobs to digest ...

I just lit up my 32-bit Ubu test machine, and ran 'systemd-analyze time' from CLI.

Code: [Select]
╭─vindsl@Zuul ~ 
╰─➤  systemd-analyze time
Startup finished in 4.295s (kernel) + 33.207s (userspace) = 37.503s

This 37.5 sec time is totally consistent with the 1000's of results I've recorded, over the years on this machine, with the classic Bootchart '/sbin/init' install.

Soooo, I think we have a winner, folks !   'systemd-analyze time' it is.  :)

Now, I'll reboot into Peppermint 7 and see if there's a diff ...

(continuing)

Hrmmm ...

Code: [Select]
╭─vindsl@Boogaloo-6 ~ 
╰─➤  systemd-analyze time
Startup finished in 4.933s (kernel) + 47.062s (userspace) = 51.995s

I might mention, I haven't optimized this 32-bit Peppermint install, except for asthetics -- custom theme, fonts, iconset, et cetera.

I ran 'systemd-analyze plot > ~/Desktop/`date "+%d-%b-%y-%T"`-plot.svg' from CLI, to see where the hold-up is ...

We have the usual suspects -- apparmor & NM -- but the 'apt-daily' service surprises me; 29.8 sec.

Guess I'll restart, and see if times improve.

(continuing)

Bingo !

Code: [Select]
╭─vindsl@Boogaloo-6 ~

Unoptimized Peppermint 7 beats highly tweaked Ubu dev branch release by 7 sec.   ;D


Here's the old girl, if anyone is interested:

Bwahahahahahaha !   Incidental finding ...

I just ran my Unity debug script (above) and noticed 'mesa-common-dev' isn't installed, by default, in Peppermint 7.

Fixed !   ;D

Okay, I'll stop now.  This post is turning into a chronicle ...

Is there any reason we should have the mesa-common development files ?

Naw !

Anyone that needs it will know how to install it, you know ?   ;)

Whoa !  You're gonna love this one !   :D

I was bored, this morning, and spent about 3 hours picking through the Linux kernel source tree -- only to find out that TRIM & NCQ/TRIM are blacklisted on my Samsung 850 EVO SSD. 

Matter of fact, ALL Samsung 8-series SSDs are blacklisted ...

LINK: https://github.com/torvalds/linux/search?utf8=%E2%9C%93&q=%22Samsung+SSD%22&type=Code

Nice, eh what ?

I couldn't believe my eyes and ran a 'sudo fstrim -av ' manually in CLI.  Sure, as shiz.  My SSD hadn't been TRIM'ed once, since I installed it.

Since TRIM & NCQ/TRIM are blacklisted anyway, I did away with the daily TRIM CRON job, and added 'libata.force=noncq' to GRUB.


Code: [Select]
<SNIP>

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="elevator=deadline apparmor=0 quiet splash init=/lib/systemd/systemd-bootchart"
GRUB_CMDLINE_LINUX="libata.force=noncq"

<SNIP>

When I got done haxoring, I did a reboot and ran:

Code: [Select]
systemd-analyze plot > ~/Desktop/`date "+%d-%b-%y-%T"`-plot.svg
...and checked the chart.  Not much difference, on this 64-bit machine, than before (11.449 sec)


BEFORE ...

A couple of hours later, I was thinking about how to improve boot times.  The showstopper was NM, as usual.  It was taking 8+ sec for the service to connect.

I'm a NM H-A-T-E-R from way-back anyway, so I decided to dump NM and install my beloved WiCD (with static IPs).

Read 'em and weep (3.176 sec) ...


AFTER ...

Bwahahahahaha !  WiCD is truly 'Wicked' !   8)

Good grief John, that's outstanding  :o!!  I think I'll switch over to WiCD.  That might be just the thing needed, to resolve the systemd, NW love hate relationship my machines are suffering from  ;).

Hmm, a website that flags you as suspect for being efficient.

"Our website contains unnecessary elements specifically designed to bog you down, you're refusing to play our inefficiency game so we're going to treat you as suspect, and bog you down with this captcha".

That's quite telling, and one heck of an admission ::)

IKR ?  BTW, for the sake of discussion, I should probably add ...

The "super-human" speed at which this machine navigates websites is primarily due to:
  • Peppermint Linux OS  (slightly haxored for additional speed, as described above)
  • WiCD network connection manager with static IPs and custom name servers enabled - Network Manager purged
  • Chromium web browser with Ghostery, ublock Origin, Disconnect, and Canvas Defender extensions enabled
  • Adobe Flash disabled

I'm currently running Peppermint 7.

WiCD is setup to use static IPs on my personal LAN - dynamic IPs on my ISP's WAN.  And, I'm currently designating WiCD to use Norton ConnectSafe public DNS servers (199.85.126.10,199.85.127.10).  I change DNS servers from time-to-time, so this varies, but Norton ConnectSafe is working well at the moment.

Chromium is a speed demon, in its own right, but a combo of Ghostery, ublock Origin, Disconnect, and Canvas Defender throws gas on the fire, so to speak.  If one decides to try this, I should warn that there ARE some built-in conflicts amongst them.  A lot of nags can be alleviated by NOT blocking (disabling) 'Advertising' and 'Site Analytics' in Ghostery, since a lot of these extensions are doing the same thing, but ... none of them, by themselves, will work independently as well as this combo.  Soooo, I put up with the occasional warning from Chromium.

Adobe Flash ... I disable it for a multitude of reasons, so I won't go into it here ('Google' it).  I don't run Flash, period.  Exclamation point !  And, I strongly suggest others don't run it, either.   ;)
