I do the same test on an intel based machine and, effectively, there
is an improvement: it tooks ~12min to achieve the installation (I add
the dmesg of that machine at the end of this mail).

Yes, sorry.
Here is the bytes/sec average of the two machines (respectively, nvidia
based and intel based) obtain when writing a 256Mo file:
# dd if=/dev/zero of=/home/jerome/buf bs=4k count=65535
65535+0 records in
65535+0 records out
268431360 bytes transferred in 33.194 secs (8086542 bytes/sec)
# umount /home
# mount /home
# dd if=/home/jerome/buf of=/var/tmp/buf
524280+0 records in
524280+0 records out
268431360 bytes transferred in 65.854 secs (4076129 bytes/sec)
# dd if=/dev/zero of=/home/jerome/buf bs=4k count=65535

Ok, so it is normal that it tooks ~12min (on the intel based machine)
to install all the packages listed previously ?

Thanks for this advice, I will keep it in mind for a future installation.

Sorry, I forgot it.
I also add it at the end of this mail.
Kind regards,
