This document describes how to install preload on Fedora 8. Preload is an adaptive readahead daemon - it will monitor which programs you use at the most. Parts of these programs will be cached to speed up their load time.

Preload is an adaptive read-ahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

For speed freaks, you could improve the boot up time using friendly GUI application, Ubuntu BootUp Manager or BUM in short. Using BUM you can make the PC load only those system services that you need, killing unnecessary ones.

What if we could use a bash script to use "apt-get" with Axel (a command line application which accelerates HTTP/FTP downloads by using multiple sources for one file) so the "apt-get" download speed would increase dramatically? Well, you can, thanks to Matt Parnell who has created a bash script which does just that.

The mail server can increase speed by placing a caching-nameserver on the mail server itself. This provides recursive lookups and a cache for the mail server to work with. The caching-nameserver does not require much resources and is easy to install.

By default there are lot of services that are running on your system (Any Fedora system) and all these services consume your resource like CPU and Memory, increase your booting time and also open your system for attack, So in order to make your system run faster and safer we need to stop all these unwanted services.

If you run scripts that require a lot of execution time it's a good idea to try to avoid letting them overload your system. You can run them via nice, but if for example your script is sending a bunch of emails your email daemon isn't running via nice and it may itself get out of control.

It has been well-documented that Ubuntu’s readahead system during boot significantly cuts down on boot time by reducing hard disk seeking via precaching commonly-used files during bootup. This feature, however, only lasts up to the GDM screen.

Performance optimization in Linux doesn't always mean what we might think. It's not just a matter of outright speed; sometimes it's about tuning the system so that it fits into a small memory footprint. You'd be hard-pressed to find a programmer that does not want to make programs run faster, regardless of the platform. Linux programmers are no exception.
