With preload, you can speed up your Computer, but, only if it is running Linux Operating System.

According to Wikipedia:

“preload is a Free Linux program written by Behdad Esfahbod which runs as a daemon and records statistics about usage of programs using Markov chains; files of more frequently-used programs are, during a computer’s spare time, loaded into memory. This results in faster application startup times as less data needs to be fetched from disk. preload is often paired with prelink.”

It is really easy to install, as it is included in all major package manager includes it. I installed it on my Arch Linux with:

sudo pacman -S preload

and then added it to the daemon list in the file /etc/rc.conf (at the end of the file).

Mine looks like this:

DAEMONS=(syslog-ng network netfs crond alsa hal !wifi-radar !fam wicd cpufreqd sensors @openntpd vnstat preload)

If you are running Debian or the famous Ubuntu, you may enter:

sudo apt-get install preload

the configuration file is at:

/etc/preload.conf

and it is very well explained, and with the default options you should be OK at first.
