I cannot replicate this. Without the patch on master (7e0da2f):

--8<---------------cut here---------------start------------->8---
$ time ./pre-inst-env guix package -A > /dev/null

real	0m5.473s
user	0m6.698s
sys	0m0.094s
--8<---------------cut here---------------end--------------->8---

And with the patch:

--8<---------------cut here---------------start------------->8---
$ time ./pre-inst-env guix package -A > /dev/null

real	0m5.778s
user	0m6.862s
sys	0m0.061s
--8<---------------cut here---------------end--------------->8---

Perhaps there's something else going on there? I'm on x86-64, if that's
useful.

Definitely agree, though in my opinion neither that nor this *really*
make `guix package --list-installed` pretty. I'm sure I could put
together an alias but it goes a long way toward making Guix look
polished to have it built-in.
