Slow speed on git clone

Sometimes when I have to clone a huge repository from Github, I find that the fetch speed can be extremely slow (KB/s).

There are two tricks I try for a quick cloning:

• Kill the command and try again. Do this a few times, see if you can get a faster connection. This works most of the times.

• Fetch only the latest revision first and then fetch the rest:

$ git clone --depth=1 git@github.com:joe/hello-world.git
$ cd hello-world
$ git fetch --unshallow

Tried with: Git 1.9.1 and Ubuntu 14.04
