Not that long ago I remember how slow Ubuntu (or GNU/Linux in general) was while booting. This was among the main “drawbacks” that I faced while trying to introduce GNU/Linux to some of my friends as they’d always compare these it with Windows and complain back.
And I can’t remember exactly what happened but some smart developers came up with a new method/script which speed up the booting time in GNU/Linux dramatically. And slowly by slowly Ubuntu too has becoming a fast booting OS and using SSD devices some even had been able to boot it under 12 seconds which is just 2 seconds away from “instant boot”!.
Few days ago Patrick Wright (Ubuntu QA team -- developers behind creating policies and other things to enhance the quality of Ubuntu) announced that Ubuntu developers will be gathering and showing-off boot times in various types of PCs that have Ubuntu installed.
Currently this web site hosts boot related speed graphs starting with Ubuntu 10.04 LTS to Ubuntu 12.04 LTS (still developing).
It only has limited amount information concerning the PC hardware. To mention a few:
*. i386 architecture (meaning 32-bit processor powered computers) only at this time.
*. Booting using Auto-Login enabled.
*. The first Boot-time is ignored as it contains first time system configuration tasks etc and it slows down the boot-time, so the speed is measured using the next time it boots.
*. Although the tested hardware will grow as time goes on but currently they have: Dell Vostro 3040, Dell Mini 10, Asus 1001px, Samsung N150 and Acer D225.
These data might not be highly accurate but if you want to see how Ubuntu progresses with its boot-speed in each release (plus they update it pretty often with current Alpha ISO daily builds too) then you might wanna check out this Ubuntu Boot Speed Tracker and I gotta say it is pretty exciting ;-).
