A Faster System

I'm always looking for ways to speed up my computer, especially when it comes to the boot process and loading applications. A good overall discussion or improving system performance is at , just remember that it focuses on the ArchLinux distro, not the Mandriva (now Mageia) distro I use. READAHEAD A useful utility is readahead . According to its manpage, readahead populates the page cache with data from a file so that subsequent reads from that file will not block on disk I/O. On my Mandriva 2010 system, the default installation of readahead places a default file at /var/lib/readahead/default.early . To create custom files based on your system, you should reboot the system and pause the GRUB menu and add the following to the command line. init=/sbin/readahead-collector This will examine your system as it boots and create a list of what files are to be loaded in the order that they are loaded.

Have a Mageia3 recovery disc on hand. From GUI Step 1. $ sudo mgaapplet-upgrade-helper --new_distro_version=4 Done. From CLI Step 1. Fully update the packages you now have installed. $ sudo urpmi --auto-update
