Very slow download from GitHub

When cloning a repository from GitHub I sometimes only get a download rate between 50-100 KiB/sec (staying stable) while most of the time I have about 10 MiB/sec. When cloning the same repository from a different machine (= different global IP) I get full speed.

Does GitHub impose a rate limit on repository cloning? The repository in question is quite big (~100 MiB) and I clone it about twice a day.

Solution 1:

I found a solution that worked very well for me.

Go to github and copy the link to the clipboard. Then open a web proxy website (https://www.proxysite.com worked for me). And paste the link (I tried with US1) - instead of downloading 670mb in 1+ hour at least, it took less than 2 minutes.

Works like a charm!!

Solution 2:

Do you have massive binaries committed in the repos? That might do it.

Otherwise, look at optimizing your CI's behavior. Instead of:

git submodule update [--recursive]

You want:

git submodule update [--recursive] --depth 1

CI doesn't need the whole repo history, just the target state. More details here: Git shallow submodules
