The procedure mentioned there is compatible with 'deb'. Though I have used Linux for software development for some time now, I am still a newbie for hands-on administration. This was my first ever experience with building and installing the kernel.
Few optimizations I applied using 'make xconfig'
- chose specific processor instead of the existing 'generic 686' and disabled SMP stuff (CONFIG_SMP not defined)
- changed timer interrupt frequency from 250 to 1000 Hz (CONFIG_HZ_1000=y) for increased responsiveness
- disabled support for lots of vendor hardware I knew I will never have: laptops, backlit display, touchscreen, etc.
- opted out unwanted file systems
- disabled lots of debug stuff--this one is not for meant for development
- opted out ATM stuff from networking support. Yes, I know what I am doing! Left most of the rest unchanged. Don't have the patience for now to make sure... Perhaps I could have turned off routing, some rarely used QoS schedulers, etc. It's just a poor desktop PC.
Kernel build time:
Removing unwanted stuff also saved compilation time by about an hour, that too, with 'nice -n 5 make make-kpkg ...'. Did not really want to simply watch the build happen. It allowed using the PC for normal daily usage. Without nice, even GDM failed to respond when I wanted to switch user :-).
Kernel image size:
Memory savings: (free -m)
12MB more user RAM available upon shell load
6M more buffered RAM available
OpenOffice Writer load time reduced by 1.25 seconds
Bootup time reduction by 1.57s
Shutdown time reduction by 3.1s
Mouse, bash output and other UI interactions seem a bit more responsive.
Nothing is known to be broken while using the freshly compiled kernel, yet :-)
Plus, now I know what is running in the kernel for having created .config from scratch before kernel code compile. Happier :-)
