Few days ago I came across rather interesting Linux distro:
Speed, performance, stability are attributes that set VectorLinux apart in the crowded field of Linux distributions. VectorLinux is a lighterweight, fast, Linux operating system for Intel-AMD x86 compatible systems and is based upon Slackware, one of the original Linux distributions. Slackware is the true ‘Unix’ of Linux distributions and its popularity stems from the fact that it is a robust, versatile and almost unbreakable system. VectorLinux has improved Slackware to produce a bloat free, easy to install, configure and maintain operating system that is second to none. We include automatic hardware configuration, unique administration tools and easy software package management via the Gslapt/slapt-get system. VectorLinux is considered to be the fastest, non-source Linux distribution on the planet!
Actually there are 4 editions of VectorLinux available: standard, Deluxe, SOHO and Live. All except Deluxe are freely downlodable.
