Great work! I depend on sharelatex/overleaf since a long time to collaborate with other people writing articles. It is especially great that your software is always available under the AGPL license.
We use mostly the git interface, not the web editor. Do you know why it is so ridiculously slow to pull/push? Like, 20 or 30 seconds when it manages to work?
If you have a lot of files or some large files it can slow things down a lot. The git server is something that's due for a revamp, but as it stands the best thing you can do for now is separate out your LaTeX content and other project assets into different repositories. (We usually see these kind of problems when people have a bunch of non-document stuff in their Overleaf project)
Thanks for the suggestion! Indeed the largest repos are the slowest to update, even when we only change a single character on a small text file. This behavior is surprising because it is not what happens in git proper, some other part of the system must be introducing the delay.
I look forward to a normalization of overleaf's git interface, most notably the ability to have regular files, symbolic links and so on.
