From what I have noticed, apt-fast is much faster than the classical apt-get package manager for Debian based distros. The apt-fast tool is a wrapper that uses axel as the default download manager. apt-fast is good for low network connections, because axel is simultaneously downloading packages with multiple connections per package.

So, in this article I will show you how to install apt-fast and how to replace apt-get with apt-fast.
Installing apt-fast:
To install apt-fast, follow these steps:
1. Add the apt-fast repo:
$ sudo add-apt-repository ppa:apt-fast/stable
2. Update the system:
$ sudo apt-get update
3. Install apt-fast and axel:
$ sudo apt-get install apt-fast axel
Replacing apt-get with apt-fast:
Next, I will show you how to replace apt-get with apt-fast. Actually, I will alias apt-get to apt-fast:
$ alias apt-get='apt-fast'
To make this replacement persistent, add the apt-get new alias to your ~/.bashrc:
$ echo "alias apt-get='apt-fast'" >> ~/.bashrc
Now, when you do this:
$ sudo apt-get install minesweeper
Your system will do this:
$ sudo apt-fast install minesweeper
