A bit of investigation showed this to be due to the first attempt to read a ref causing the packed refs to be loaded. In my test repo the packed-refs file has over 9000 entries, but I still thought that it would load faster than that. It turns out that the overhead is from sorting the refs when building the ref_list. If I remove the code for sorting the entries I lose that initial 1s delay, without appearing to break anything in the fetch. However I assume that it's there for a reason ...


Actually, it's worse than that ... I forgot about the other end. If I point fetch at an upload-pack with the sorted removed the time goes down by another second. So that sorting accounts for 2 of the 3s ...
