Git pull is very slow... Why?

I had the same issue. For me this was a IPv4/IPv6 issue. I fixed it forcing SSH to use IPv4.

Set "AddressFamily inet" in /etc/ssh/ssh_config to force IPv4 connection. Then restart ssh client sudo service ssh restart

More info here.

I have had the same issue when I was dealing with thousands of small files. The thing that fixed it for me was to set the postbuffer in git repo's config

git config http.postBuffer 524288000

Instead of uploading with 18KB/s it suddenly went the full bandwidth

I tried all solutions in this thread with no luck. I tried using git protocol 2 at the suggestion of a coworker, which ended up being very effective (went from waiting 3 minutes for pulls/pushes to start to a few seconds)

git config --global protocol.version 2
