Bonjour,
Il y a une semaine, la synchronisation de l'arbre a pris 30 minutes à la louche ; j'ai trouvé ça long.
Cette nuit, elle a pris deux heures !
C'est la phase de vérification de /var/db/repos/gentoo/.tmp-unverified-download-quarantine qui est très longue.
Je n'ai pas déclaré d'autre dépôt que le dépôt principal Gentoo.
Il y a un source et un binaire de déclaré.

Salut !
Ton /var/db/repos/gentoo ne serait pas sur un vieux HDD mécanique, des fois ? |

J'ai commenté des modifications de FETCHCOMMAND_RSYNC et RESUMECOMMAND_RSYNC
(voir https://forums.gentoo.org/viewtopic-t-1170224.html)
| Code: | $ grep -i command /etc/portage/make.conf
#FETCHCOMMAND="wget -t 3 -T 60 --quiet --passive-ftp -O \"\${DISTDIR}/\${FILE}\" \"\${URI}\""
#RESUMECOMMAND="wget -c -t 3 -T 60 --quiet --passive-ftp -O \"\${DISTDIR}/\${FILE}\" \"\${URI}\""
#FETCHCOMMAND_RSYNC="rsync -LtvP --quiet \"\${URI}\" \"\${DISTDIR}/\${FILE}\""
#RESUMECOMMAND_RSYNC="rsync -LtvP --quiet \"\${URI}\" \"\${DISTDIR}/\${FILE}\""
$ |
J'ai un meilleur résultat :
| Code: | $ time sudo eix-sync -a
...
* Time statistics:
656 seconds for syncing
2 seconds for eix-update
3 seconds for eix-diff
662 seconds total
real 11m2,089s

Je dois attendre demain pour essayer une commande time sudo emaint sync --auto
Je ne comprends pas encore l'amélioration. |

On ne va sûrement pas te ban si, exceptionnellement, tu fais plus d'un sync par jour ! 
Les disques mécaniques sont considérablement plus lents que les SSD (même les SSD SATA !).
Vu qu'ici, la vérification implique la création de dizaines de milliers de liens physiques dans le répertoire temporaire, tu gagnerais certainement du temps en plaçant ton /var/db/repos/gentoo sur un SSD.
De plus, en écriture, le RAID1 ne t'apporte rien niveau vitesse, que du contraire ! |

Bonjour pti-rem,
As-tu essayé de synchroniser via GIT plutôt que RSYNC ?

Bonjour xaviermiller
J'essaierai de synchroniser avec GIT un de ces quatre.
Je crois avoir compris que plus j'espace les syncs, plus celles-ci sont longues.
J'ai constaté l'allongement après avoir choisi de les espacer d'une semaine au lieu de deux jours environ.
Je ne m'attendais pas à avoir une sync longue de deux heures.
Je crois que les FETCHCOMMAND_RSYNC et RESUMECOMMAND_RSYNC modifiées n'y sont pour rien.
C'est vrai que c'est ma première machine non-SSD pour /var/db/repos/gentoo
Je n'ai pas de SSD pour elle.
Merci |
