It occurs to me that there might be cases in which each way works better.
>From an experience about 3½ years ago[1], I drew a conclusion (which may have been erroneous, or may have changed in newer git releases) that the http protocol handler was not as bidirectional: the client was less able to negotiate with the server exactly which objects it already had and which were wanted, leaving the server to send a needlessly large mass of stuff by default, whereas git-over-ssh was able to negotiate a tiny minimal pack file to transfer. My experience was in the context of keeping a local clone that was shallow (the project repo had enormous history going back aeons, of no use for me to test small patches on HEAD), and it seemed possible that the cutoff points for the shallow history were among the information that did not get effectively conveyed to the server over http. I have not tested that again lately, or with the postgresql repo. I guess I could, without much trouble. -Chap [1]: https://stackoverflow.com/questions/25954622/a-way-to-keep-a-shallow-git-clone-just-minimally-up-to-date
