Supposed Ubuntu Speedups
After seeing Lifehacker blog about a number of Ubuntu speedups, I decided to test some of them to see their actual effectiveness.
The test machine was a Lenovo T61 with a Core 2 Duo T7500 @ 2.2 ghz and 3GB RAM. All boot times are from the grub menu (started when I pressed enter to start the boot) to the appearance of the login screen. I started with a completely fresh installation of Ubuntu 8.10 which I updated and rebooted 3 times. The default settings are "concurrency=none" in /etc/init.d/rc, but I'm unsure of the default readahead settings. It's possible it tries to do create a profile after installation, but I have no proof of that, so I assume there is no profile.
