My internet speed to github was never fast, and it's lingering at 50kb/s (my internet speed is 20mbit which is not very fast but still much faster than this). The repository is multi-gb by my estimates, so it'll take a very long time.
Does git support downloading the objects using multiple-threads so I can max-out my internet speed?
You can at least try and mitigate the issue, with a shallow clone (meaning not cloning the all history):
git clone --depth 1 <repository>
Make sure to have a git 1.9+, as I explained in "Is git clone --depth 1
(shallow clone) more useful than it makes out?".
Note: Git 2.5 (Q2 2015) even supports a single fetch commit!See "Pull a specific commit from a remote git repository".
