For desktop systems an optimised boot process isn't much of an issue but for embedded systems it is critical. You don't want a client asking "Why does it take a minute for my VoIP server to reboot?" "Why does my multimedia player take two minutes before I can watch a movie?" These people can't sit at a console and watch all the pretty boot messages scroll by. All they can do is sit and wait and get annoyed because their system hasn't come back up yet. Articles like this are interesting reading for anyone wanting to squeeze every last second out of the boot time of their embedded linux device.
Another big contributor to boot times that the article didn't cover is the amount of time spent sitting in the BIOS. If you're serious about shaving off a few more seconds you might also want to look at http://linuxbios.org/.
The "system performance" he is referring to is on your development machine, i.e. where you are running kgdb. Of course compiling your kernel with -g will affect performance on the target machine! By not running a development kernel on your development machine you are not affecting your system's performance. I don't know about you but it really affects my system's performance when the kernel panics.

The expansion set outsold the original??? This says to me that there are a heck of a lot of pirated copies of D2 out there. But wait a minute.. why buy the expansion when you've already not paid for the original game?
