I'm running Linux Mint 14 on notebook. This notebook is rather old and really weak. Linux Mint shows better performance than Win7, but newertheless it's far from perfect. What can I do to speed up my OS?
Go through and disable any services you don't need. I suggest checking out the Linux Mint forums for help on that. I don't know your level of Linux expertise.
For example, if you don't have any bluetooth devices, disable anything bluetooth.
