1. Tool to tune system for optimal performance Powertweak is a tool for tweaking Linux systems to peak performance. It tunes PCI devices to use optimal settings and enables performance enhancing features of the CPU(s). To use all of powertweak's features you need to be running a Linux kernel which supports the /proc/bus/pci and /dev/cpu/<n> interfaces. This package contains the daemon that needs to be run to do the actual tuning. You need either powertweak-text or powertweak-gtk to choose which tweaks you want to perform on your system in addition to this package. The package powertweak-extra contains some additional tweaking plugins. From Debian 3.0r0 APT
