I gave this branch a go. There's a performance regression as I'm getting a clone speed of about 100 KiB/s while with the previous patch I got around 20 MiB/s. The culprint appears to be a very large number of stat() calls on ".git/objects/info/alternates". The call stack is: -> quick_has_loose() -> prepare_alt_odb() -> read_info_alternates()
