Hello Guix,
I am having performance issues with Guix operations since a few weeks.
Concretely, any call to `guix pull` takes approximately 10 minutes to finish,
on a reasonably powerful machine (Core i7, 12 cores, 16G RAM, 1 TB SSD drive
with plenty of available space), and this even if rerun `guix pull` when
nothing has changed. I did not note the precise time or context where things
changed, unfortunately, but not long ago this was way under a minute for a
pull to finish, with the same channels.
In the same context, it takes 3 minutes for a `guix home reconfigure` with a
small home profile and 5 minutes for a `guix system reconfigure` with a rather
big profile, when there is nothing to update.
Is this kind of performance normal ? And if not, how can I diagnose the
problem to understand what takes that much time ?

Hi,
I’m fairly new to the Guix scene, but recently there was a discussion about it
on devel-guix@gnu.org mailing list. So far it works as designed, because every
time you use guix pull, they have to recompile every package definition.
I’m a complete pleb when it comes to guile development, so take it with a heavy
grain of salt.
You can check for more information in the devel archive:
<https://lists.gnu.org/archive/cgi-bin/namazu.cgi?query=Guix+pull+speed&submit=Search%21&idxname=guix-devel&max=20&result=normal&sort=score>
Hope that helps,
Ignas

Thanks for the pointer. Now I think I understand the reason for this
behaviour: Guix has to compile the whole set of modules, including all package
definitions, and it is rather slow at that. So I guess I won't expect
significant improvement in the near future, but at least it's not an issue
with my particular installation!

If it is not already the case, you might be interested by:

I didn't answer to that at the time, but I do use channels with substitutes as
described in the documentation. I only have the default channel as desribed
there, plus a small custom channel in a local git repository where I put
definitions for custom packages and for third-party packages that I need
(which I intend to propose for integration in Guix itself eventually).
I actually use another channel with less libre kernels and firmwares, but I
disabled it for testing pull times (and it doesn't change things much).
Now, even if I didn't expect a significant improvement, I am still badly
surprised by the behaviour of Guix: one month ago, any `guix pull` took 10
minutes to complete, and these days it takes 40 minutes (the same command, on
the same machine in the same conditions). When running a second `guix pull`
while the channels are unchanged, it takes "only" 6 minutes of computation
before telling me that there is nothing to do.
How is it possible that things are four times slower over just one month ?
Did the package collection increase that much ?
Were there structural changes that caused a loss of efficiency ?
Or might there actually be someting wrong with my setup, and in this case how
could I diagnose it ?
Updating Guix is becoming painful, and if run times continue with their
exponential growth, it will become simply unusable.

Hi,
If I read correctly, your machine is:
a reasonably powerful machine (Core i7, 12 cores, 16G RAM, 1 TB SSD drive
with plenty of available space)
Correct?

Using my desktop machine (i7, 16 cores, 64G RAM), I get:
+ plain “guix pull”: ~10min
+ redo “guix pull” with the same revision: ~2min
