Boot times - SSD's ROCK!

[oshunluvr]

I rarely shut down or reboot my system and when I do, I don't sit and watch it. Today, I did a power off reboot and roughly timed it (analog watch) just for kicks.

My BIOS has a built-in pause after detecting IDE devices (dvd-rom) and detects and does a SMART check of the four SATA drives. Plus, I have several installs on my system so I use a dedicated GRUB install to make grub updating easier (details are posted elsewhere). The defaults lead the computer to my main install.

So, BIOS wait and two GRUB waits until the real business of booting begins.

Time table:

14:37 - pushed power button
15:08 - BIOS finished and 1st GRUB begins
15:17 - 1st GRUB hands off to 2nd GRUB
15:46 - Login screen presented

1 minute, 9 seconds. Not too shabby considering all the overhead. Presumably with no IDE drive and only a single install and GRUB menu suppressed I could get to login in 25 seconds give-or-take. I swear it took around 3.5 minutes prior to the SSD and without the dual GRUB setup.

I timed the login to my Kubuntu 12.04.3 from power on to login screen -- 33 seconds.

EDIT: Correction -- 16 seconds to the login screen, 17 more seconds to a working KDE desktop.

They are really awsome when it comes to bootup times
I have one installed in my Toshiba i5 laptop and my iMac desktop with a very modest Core2duo prosessor and Kubuntu only, and both bootup times are just phenomenal.
And with upgrades, once it downloaded all its stuff, just races through the installation of it.
At work, where i am still stuck with XP, and booting over a network, 10 minutes is no exeption between turning it on and having a usefull desktop.

I must confess that I do not have such an elaborate system. My Laptop is an ASUS R501VM Core i7 3610QM and I have a Samsung 840 Pro Series 256GB SSD with Kubuntu 13.10 installed. Using my stopwatch I found it difficult to get accurate times, so my approximate times are:

7.6s - Power On to Grub Menu for Selecting Kubuntu etc.
5.5s - Enter to Select Kubuntu and then Login Screen,
7s - Very Approximate time from Login to Functional Desktop

When I boot my system in front of M$ devotees, I say nothing and hope they notice the speed to boot.

Edit:
After whatthefunk gave his time, I was challenged to measure power on to login screen and kept hitting enter to skip the grub menu. I was about 10s for this case with some times measured at 9.5s.

My power off time is about 13s! I sometimes wonder if my NFS connections are resposible for the extra time.

It is great to see all the fast times with 13.10 .

About 9s from power on to login screen.

My little HP 110 Mini and my wife's Dell Vostro are desktop in 14-17 secs and off in as little as 8.

My Dell "Powerhouse" laptop with XP is about 8 minutes to log in screen. I have powered up the XP Dell, then powered up the linux Dell, log into the linux Dell, checked something, logged off and powered down the Linux Dell and STILL didn't have a log in available yet on the XP Dell!

Pah, you think that's fast, you should see my PC boot (read sig').

Really? You have to boot the OS over the network?

[GerardV]

It appears so, Steve. It wil not boot without a network connection, although it looks that XP is installed locally.

I don't understand why this surprises you so much Steve, that's actually fairly common, they probably do it for a number of reasons.

Ah, Gerbil power! Those little rascals are FAST!

MontaVista Achieves Ultra-fast One Second Linux Boot Time in Embedded Industrial Applications

Yes, from 2009. Yes, not for practical 'every man' Linux. But still...

XP was never designed for booting over a network, where the OS binaries stream from a central location into a desktop terminal each time the terminal is switched on. Note this is not the same as running a remote session, like over VNC or a Terminal Server.

But GerardV wrote that XP appears installed locally, but won't boot without a network connection. My guess: poorly-configured roaming profiles combined with a slow LAN. I've seen this a zillion times.
