In this guide, we will see some tips that may speed up your system boot time:

1. Preload

If your programs take much time to open, you can use Preload, which is a utility capable of making your programs open rapidly. Preload is available in the official Ubuntu repository, you can install it via your web browser by accessing directly this link, or launch the terminal and issue this command:

sudo apt-get install preload

Once installed, you don't have to start Preload or even configure it. Preload loads your programs by using your computer installed RAM (Preload only uses 10% of your RAM) to increase program execution speed. For better system stability and performance, it is recommended that you have at least 1GB of RAM.

After testing this utility, I have noticed a significance increase in speed when launching some programs like GIMP.

2. Using All CPU Cores During The System Booting Process

If you have a multi-core processor, then follow these instructions:

- Via the Terminal edit this file:

sudo gedit /etc/init.d/rc

- Locate this line:

CONCURRENCY=none




And replace it with this line:

CONCURRENCY=shell




- Save the file and close it.

3. Removing Unnecessary Packages

Via the Terminal, run this command:

sudo apt-get purge brltty-x11 min12xxw brltty ttf-indic-fonts-core ttf-kacst-one ttf-khmeros-core ttf-lao ttf-punjabi-fonts ttf-unfonts-core foo2zjs

Note: These tips are tested under Ubuntu 11.04/ 10.04 / 10.10
