I have a repo with one "big" file (~280 Mb), only this file is tracked by lfs. When I try to push it, push is extremely slow, around 20 KB/s - and if I wait, it only gets slower.
I tried using git for windows - git version 2.28.0.windows.1 with git-lfs/2.11.0 (GitHub; windows amd64; go 1.14.2; git 48b28d97) and I tried Ubuntu with git version 2.28.0 and git-lfs/2.12.0 (GitHub; linux amd64; go 1.13.4) - with equal results.
I also tried pushing by ssh and https, and setting git config http.version HTTP/1.1 - no difference.
I'm pushing to github (not sure if that matters); bandwith limit doesn't seem to be the issue.
