Gitlab push very slow - Gitlab-CE

Question

Gitlab push is very slow, Is there any settings I can modify on the internal gitlab-ce server that can make the git push much faster? Right now the push speed is 13.00 KiB/s.

I have some large repo still hasn't committed to gitlab due to its speed.

setting git config http.postBuffer 524288000 gets stuck at POST git-receive-pack (37437584 bytes) for very long time.

setting git config http.postBuffer 5242 starts pushing but at very low speed.

`Writing objects:  76% (73/95), 3.72 MiB | 13.00 KiB/s`

I read that git config http.postBuffer doesn't make it faster since only the local buffer is faster but the push still depends on the server accepting speed. So wondered if anything can be tuned on the server side?

Answer 1

Disabling IPv6 and rebooting the gitlab server seems to have fixed the issue.

One more reason it could be slow is if you're using IPTABLES and don't have a accept rule for loopback interface like this -A INPUT -i lo -j ACCEPT.
