Debian LXDE frugal install (auto logs in 'user') - using mobile phone stopwatch and setting record points
0.18.4 BIOS ends
0.27.09 PC splash screen ends
0.30.73 Grub4dos menu.lst ends (after default 3 second timeout)
1.08.40 Desktop fully loaded and panel net connection icon pops up (ready to go).
... so 1 minute 8 seconds to desktop
I'm guessing those with a couple/few second 'boots' are from hibernated image restores not full cold boots?
My grub4dos boots initrd/vmlinuz which loads filesystem.squashfs (main filesystem all contained in a single sfs). The above default boot is a read-only session with all changes stored in ram, with option to flush those changes to disk (savefolder) ... or not. Another script provides remaster live session ... to create a new filesystem.squashfs with all changes merged into that. Timing of remaster time ... 1 min 48 seconds (mksquashfs uses lzo level 1 compression). 1.9GB filesystem.squashfs filesize (full debian jessie lxde, with firefox, chromimum, libre, audacity, openshot, blender, inkscape, skype, masterpdfeditor major applications included).
Operationally Libre calc takes around 3 seconds to load the first time (read from disk/IO), near instant on subsequent loads. Firefox typically takes around 4 or 5 seconds to load, no matter if its been loaded earlier in a single session. Most other programs are near instant, except skype which takes around 5 seconds the first time its run, 1 or 2 seconds on subsequent loads.
