Interesting, so we should profile that step and see what can be done. I
suspect it=E2=80=99s I/O-bound, but maybe we can at least improve feedback.
Thanks,

It does take some time, but since I can see the output change from grafting=
to grafting, I at least can tell guix is doing something, so I just let it=
be.
Compared to grafting, the last step "construyendo perfil con X paquetes..."=
("building profile with X packages..."), just stays there without change f=
or several minutes, so it actually seems slower to me. Initially, I thought=
that guix had frozen.
Also, even though, the "building profile" step has a throbber (| / - \) to =
indicate that something is being done, it frequently stops in one of the fr=
ames of the sequence and stays there until the end.

Clever workaround! What are now the performances on previous examples

Hum? Interesting=E2=80=A6 well weird! If it is not a =E2=80=9Cmorphism=E2=
=80=9D then it is not
really an updater. Anyway.
I am curious about the comparison:
time(update-mime-database(X =E2=88=AA Y))
vs
time(update-mime-database(X)) + time(update-mime-database(Y))
vs
time(update-mime-database(X =E2=88=A9 Y))

=E2=80=99shared-mime-info=E2=80=99 is simply a package, right? So what doe=
s it means:
=C2=ABFind a way to avoid reprocessing 'shared-mime-info'=C2=BB in:
--8<---------------cut here---------------start------------->8---
;; the database. TODO: Find a way to avoid reprocessing
;; 'shared-mime-info', which is the most expensive one.
[...]
(invoke #+(file-append shared-mime-info
"/bin/update-mime-database")
destdir)))))))
--8<---------------cut here---------------end--------------->8---
? Well, I miss why and how =E2=80=99shared-mime-info=E2=80=99 could be the=
culprit here
or what could be improved with =E2=80=9Cshared-mime-info=E2=80=9D? Maybe r=
eplace the
=E2=80=9Clazy reference=E2=80=9D by a strict one if it makes sense.
All the best,
simon

Based on these observations, I added a fast path to the
=E2=80=98xdg-mime-database=E2=80=99 hook:
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=3D76ea70bd70aeb7657=
0445c11cea2f98139192b54
It=E2=80=99s down to 0s in the common case where the profile doesn=E2=80=99=
t contain any
packages providing =E2=80=98share/mime/packages=E2=80=99.

On closer inspection, the time-consuming bit is processing
=E2=80=98share/mime/packages/freedesktop.org.xml=E2=80=99 (from =E2=80=98sh=
ared-mime-info=E2=80=99),
which is quite large and leads to the creation of hundreds of file. We
end up re-processing it every time. This is particularly wasteful
because the =E2=80=98shared-mime-info=E2=80=99 package already contains the=
result of
applying =E2=80=98update-mime-database=E2=80=99 to itself.
Unfortunately, AIUI,
update-mime-database(X =E2=88=AA Y) =E2=89=A0 update-mime-database(X) =E2=
=88=AA update-mime-database(Y)
(For example, the files
=E2=80=98share/mime/{globs,magic,XMLnamespaces,subclasses,aliases,types,gen=
eric-icons,icons,treemagic,mime.cache}=E2=80=99
concatenate info from X and Y.)
So it would seem we cannot simply used the pre-built database from
=E2=80=98shared-mime-info=E2=80=99 and merge it with that of the other pack=
ages, at
least not without changing =E2=80=98update-mime-database=E2=80=99 or re-imp=
lementing
parts of it on our side.

It is. Small profiles operations are much faster than large profiles.
Attached is a slightly trimmed version of the manifest I currently use
for my user profile, if you'd like to benchmark it on your system.

I'm betting that the part to optimize is:

#:log-port (%make-void-port "w"))

They do, and this is indeed what takes time. But, this doesn't stop
motivated wizards from implementing our own database generator in Scheme
that would do the same. Ludovic had done just that for the man-db
database generator. The custom code in Guix can do it much faster that
it initially could back when it was relying on man-db to do that (that's
also probably the reason why we have issues such as
https://issues.guix.gnu.org/38838; perhaps the generated database is
slightly different -- but that's another topic :-)).
Thanks,
Maxim

I've noticed on multiple occasions that using Guix on traditional spinning drives can be quite slow. On my home machine, will is still relying on 2 x 1 TB spinning drives in RAID1, rebuilding my user profile, which contains 182 entries, takes on average about 20 minutes, even when there are no packages to be built: --8<---------------cut here---------------start------------->8--- $ time guix package -i perl --max-jobs=1 The following package will be upgraded: perl (dependencies or package changed) The following derivation will be built: /gnu/store/lhywla1z2zcz16df4hbvvvngr9zmswr7-profile.drv building CA certificate bundle... building fonts directory... generating GLib schema cache... creating GTK+ icon theme cache... building cache files for GTK+ input methods... building directory of Info manuals... building database for manual pages... building XDG desktop file cache... building XDG MIME database... building profile with 182 packages... real 19m0.126s user 0m5.648s sys 0m0.333s --8<---------------cut here---------------end--------------->8--- Most of the time remains spent after the message 'building profile with 182 package...'. That part seems IO-bound, with the spinning disks grinding heavily and the CPU mostly idling. The rest of the time (3 minutes), was used by the profile hooks. The same operation on a second, more modern machine equipped with M2 SSDs does much better and takes about 1 minute to accomplish the same, so it seems the bad performance can be mostly attributed to the much slower disk seek times of the spinning disks. On the older machine, two profile hooks are also sticking out w.r.t. the time they take (they take more than one minute opposed to a few seconds): --8<---------------cut here---------------start------------->8--- The following profile hook will be built: /gnu/store/08fanpydi7z4i3qnlqbr8iz23zdgsamw-manual-database.drv building database for manual pages... Creating manual page database...

After that we could look into the two above profile hooks. Thanks, Maxim
