FWIW: I’m using GUIX_DAEMON_SOCKET=guix:// since a few days.  It allows
for a simpler “guixr”, which now only prints extra info and refuses to
run on the login node.  It’s really nice!

I haven’t noticed any difference in performance, but I certainly could
test patches.

Performance differs a lot for different packages.  “guix build bwa” (~ 7
seconds) is a lot faster than “guix build python2-numpy” (> 40 seconds),
for example.
