Mmhhh, je suis septique avec tes options de no/low delay, ça n'incite pas smbd à remplir ses buffers au max.

Sans les options  no/low delay, c'est encore pire avec la valeur doublée (16384) retour à l'anémique 16-20 Mo/s. Je crois que je ne pourrais pas avoir mieux que 50, ce qui est déjà pas mal.

Tu peux nous filer le résultat de testparm -v ? Attention, il faut appuyer sur entrée pour avoir le résultat.

Il y a d'autres paramètres de buffer à potentiellement ajuster.

Je dois dire que je n'ai jamais vu une telle flopée d'options (générales) configurées. En général, chez moi, c'est beaucoup plus court, une vingtaine d'options au max. Avec tant d'options, c'est difficile de s'y retrouver. Mais bon, il affiche peut-être les options fixées par défaut ?

Sûrement oui, car je n'ai quasiment rien de configuré dans smb.conf  :
[global]
dns proxy = No
log file = /var/log/samba/log.%m
server string = serveur samba
invalid users = root
socket options = SO_RCVBUF=16384 SO_SNDBUF=16384
os level = 20
syslog = 0
max log size = 1000

@alain_p: l'option '-v' affiche les options par défaut/cachées.

@Renaud: tu peux tenter de modifier:

max xmit = 16644 -> 32768
socket options -> à augmenter aussi du coup à 131072
server max protocol = SMB3 -> j'essaierai SMB2

C'est toujours pas ça  :( Environ 37 Mo/s.

Une fois les options retirées ça retourne à 50 Mo/s stable. Je crois qu'on ne pourra pas faire mieux.

Il faudrait que j'essaie openmediavault, vu qu'elle est spécialement pensée pour faire un NAS, peut-être qu'il y a des optimisations.

J'avais d’ailleurs pensé faire comme ça au début, mais vu que je voulais faire un serveur "multi services", il y avait des confits, notamment concertant les serveurs web, du coup je suis parti d'une debian netinstall. Je pourrais à la limite virtualiser les 2 mais les perfs risque d'être encore plus mauvaises.

Le top serait d'avoir 2 machines, mais je suis un peu limité niveau place.

Les paramètres que je t'ai donné sont ceux de mon freenas, qui est lui-même autant optimisé que OMV. Je sature du Gb sans pb.

C'est ma config qui a un problème alors... Tant pis.
