ToriOS – ultra-light, based on Ubuntu 12.04 LTS and JWM

If you want to try a new ultra-light distro, try ToriOS, based on Ubuntu 12.04 LTS and the window manager JWM. It uses only ~ 90 MB RAM or less, when running idle after booting (the RAM usage varies depending on the computer hardware). See this comparison, where Lubuntu Trusty used 123 MB. If you want to run ToriOS in old hardware with a weak processor and low amount of RAM, you need ultra-light application programs too. In a bit more powerful computer and with more RAM, it will be very fast, and you can use the standard linux application programs.
