You can easily make apt-get use a download accelerator for faster upgrades. Using apt-fast, which is simply a script that uses Axel, a command line application which accelerates HTTP/FTP downloads by using multiple sources for one file.
sudo apt-get install axel cd ~/Desktop wget http://www.mattparnell.com/linux/apt-fast/apt-fast.sh mv apt-fast.sh /usr/bin/apt-fast sudo chmod +x /usr/bin/apt-fast
Now you can use apt-fast instead of apt-get and it will use our download accelerator to speed things along.
sudo apt-fast install htop sudo apt-fast update
