VectorLinux is here to save the IT-damsel-admin-home-user in distress by providing a very fast distro, new kernel, new packages optimized for performance. Ok do not expect to run OpenOffice 3 on a pentium II 300 MHz but you get my point. As fast the OS is concerned everything is fast. It is based on Xfce Desktop and it looks rather nice. On the downside it still uses Lilo by default so if you have all your machines running with grub you might have to spend some extra time twiking.
According to the developers the requirements for the different editions are:
Standard Edition: Pentium 200 or better, 96MB RAM, 2.1GB hard drive space for system only, more for your data.
SOHO Edition: Pentium 750 or better, 128MB RAM minimum, 3.1GB hard drive space for system only, more for your data, video and monitor capable of 1024x768 resolution at 24 bits color.
Light Edition: Pentium 166 or better, 64MB RAM minimum, 1.8GB hard drive space for full system - more for your data.
Live Editions: Pentium 750 or better, 256MB RAM minimum, video and monitor capable of 1024x768 resolution at 24 bits colour. For the Beryl version you will need a modern video card.
The new version 6.0 was just released offered into 2 different packages. One free and one that costs 25$. The difference is that in the pay version you get to have 15 days installation and configuration support and some extra packages by default. A live CD is available, as well, if you just want to try it out without installing.You can download it from here.
