By default Ubuntu is fast enough. But that does not mean that you should not wish it to be even faster. As you might have noticed that some of the programs or applications in Ubuntu take relatively high time in starting. This may be annoying if you use the concerned program frequently. So if you wish your Ubuntu to be faster with these applications, Preload is the must have package for you.
What is Preload?
Preload is a daemon application and runs in the background. Preload analyzes the user behavior and tracks what applications are run frequently by the user. Based on these analysis, it predicts what application the user might run next and fetches those binaries and their dependencies into memory and hence increases the startup time of the application.
How to install Preload in Ubuntu?
Type the following command in terminal (ctrl+alt+T):
sudo apt-get install preload
Well, that is it. You don’t need to do anything else. After a reboot it starts running in background and magically improves the application startup speed. I have not noticed any side effects of Preload as of now, I will update if there exist any. Cheers
