Hi everyone,
I noticed something after buying several laptops.
With the same configuration/installation of Linux, the kernel boot time
is really different and it looks like that it depends on the architecture
and probably more about the hard disk.
(When I talk about "kernel boot", I talk about these plots (like this
---> ".........")
coming when Linux boots)
I have a 7200rpm hard disk and it takes about 20-25 seconds just to
"print" that
plots.
The boot image is about 2.6MB and I guess that the image should be
loaded on
cache and then get executed but it looks like that it's loading while
executing.
Does anyone knows how to accelerate that kernel boot up? Any idea?
Have you turned off unnecessary services that start up during the boot
process (printers, servers, etc.)?
Try compiling a smaller kernel image and be sure to disable all
unnecessary kernel options.

Yes unecessary services are turned off but my issue is more
during the startup of the linux kernel (when it load and executes
only the kernel.....not yet the services).
As I said, with another laptop with the same image it was really
faster.
And I solved the issue by using the "compact" option in /etc/lilo.conf.
Does anyone know exactly what this option is doing to make things go
real faster?
