I was using vanilla git, as of 10 minutes before I sent the email. Top of tree is 154d3d2dd2656c23ea04e9d1c6dd4e576a7af6de.

Secondly, what's the problem? Sure, I could special-case the local case, but do you really want to have two _totally_ different code-paths? In other words, it's absolutely NOT a complete waste of time: it's very much a case of trying to have a unified architecture, and the fact that it spends a few seconds doing things in a way that is network-transparent is time well spent.

Put another way: do you argue that X network transparency is a total waste
of time? You could certainly optimize X if you always made it be
local-machine only. Or you could make tons of special cases, and have X have separate code-paths for local clients and for remote clients, rather than just always opening a socket connection.

Poor example... sure it opens a socket, but X certainly does have a special case local path (mit shm), and they're adding more for 3D due the massive amount of data involved in 3D.

We do end up having a special code-path for "clone" (the "-l" flag), which
does need it, but I seriously doubt you need it for a local pull. The most expensive operation in a local pull tends to be (if the repositories are unpacked and cold-cache) just figuring out the objects to pull, not the packing/unpacking per se.

Well, I'm not overly concerned, mostly curious. The pack+unpack step (a) appears completely redundant and (b) is the step that takes the most time here, for local pulls, after the diffstat.
