The “speed up your distro” article will come out soon. Meanwhile, I would like to thank everyone who voted.
I intend to split the main article into a series of three sub-articles: Improving boot speed, making the system faster and lighter and window-manager specific optimisations. Due to some differences among distributions, it is impossible to cover everything, so the distros this article will deal with are: Arch, Debian, Fedora, Mandriva, SuSE and Ubuntu. Since most other distributions are either based on one of these, or are completely different, this should be enough for the great majority of users. If you have a request for a different distribution just post a comment and I’ll look into it.
