clipped from www.extremetech.com Hacking Ubuntu to Improve Performance This feature includes various hacks to boost Ubuntu's performance, such as viewing running processes, identifying resources, finding process startups, tuning kernel parameters, and speeding up boot time. This is a complete chapter in the ExtremeTech book "Hacking Ubuntu: Serious Hacks Mods And Cusomtizations." In order to fine-tune your system, you will need to know what is currently running, which resources are available, and when processes start up. From there, you can tweak configurations: disable undesirable processes, enable necessary housekeeping, and adjust your kernel to better handle your needs.
