Bonsoir,
Je me suis monté l'an passé un serveur basse conso avec une CM asrock Q1900-ITX sous debian, et bien que pas très puissant, je suis étonné de la différence de performances entre samba (partages Windows) et NFS.
Avec samba, je ne dépasse pas les 16 Mo/s que ce soit en lecture ou écriture, alors qu'en NFS c'est d'une rapidité, au moins 50 Mo/s en écriture (en augmentation avec le transfert) et en lecture c'est 80 Mo/s.
Le jour et la nuit, littéralement. Alors je sais que le protocole SMB a tendance à être plus pourri que NFS, mais quand même, faire à peine plus que 100 Mb/s je trouve ça léger. Et sous windows directement c'est encore pire, je me tape des transferts à 8 Mo/s !
J'ai contrôlé les ressources systèmes pendant les transferts et le CPU tout cœur confondu n'est même pas à 50% (aucun cœur n'est utilisé à fond).
Est-il possible d'améliorer ça ou c'est une cause perdue ?
Merci d'avance.

Déjà ça vient pas du CPU: mon Atom C2550 n'est guère plus performant d'après CPUboss.
CPU tout cœur confondu n'est même pas à 50% (aucun cœur n'est utilisé à fond)
T'as regardé avec quoi ?
TODO de tests à faire sur le serveur:
- test d'écriture en local de 1Go: dd if=/dev/zero of=/tmp/test bs=1M count=1024
- pendant une copie SMB: lances un "iostat 2" et fais-nous un petit top aussi
- smarctl -a /dev/<disque> (probablement sda ou sdb)
- hdparm -I /dev/<disque>
- hdparm -t /dev/<disque>
-
Pour le cpu j'ai regardé avec htop. Avec top le process smbd occupe 24% du cpu (voir image en PJ).
La commande hdparm -I ne correspond à aucune option, tu voulais savoir quoi exactement ? Pour le reste voici :
root@serveur:~# dd if=/dev/zero of=/data/test bs=1M count=1024
1024+0 enregistrements lus
1024+0 enregistrements écrits
1073741824 octets (1,1 GB) copiés, 7,73777 s, 139 MB/s
root@serveur:~#
Le disque est plein à 80% donc c'est à mon avis normal que le test d'écriture sois un peu limite.

Au vu des warning, je pense que ma config samba est à optimiser, j'avais testé il y a un moment différents paramètres et je n'y ai pas retouché depuis.
EDIT : Après avoir commenté la ligne des options TCP, ça turbien à 40-50 Mo/s, youpi ! :D Et il y a peu je suis aussi passé a un switch gigabit, c'est donc pour ça que je ne voyais aucune différence quand j'étais en 100 Mbps.
C'est pas aussi rapide que NFS mais y'a un très net progrès 8)

WARNING: socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=8192 SO_SNDBUF=8192
This warning is printed because you set one of the
following options: SO_SNDBUF, SO_RCVBUF, SO_SNDLOWAT,
SO_RCVLOWAT
Modern server operating systems are tuned for
high network performance in the majority of situations;
when you set 'socket options' you are overriding those
settings.
Linux in particular has an auto-tuning mechanism for
buffer sizes (SO_SNDBUF, SO_RCVBUF) that will be
disabled if you specify a socket buffer size. This can
potentially cripple your TCP/IP stack.
Getting the 'socket options' correct can make a big
difference to your performance, but getting them wrong
can degrade it by just as much. As with any other low
level setting, if you must make changes to it, make
small changes and test the effect before making any
large changes.

A 50Mo/s, c'est possible qu'un Core sature sinon ça veut dire qu'on peut encore gratter.
SMB est bien plus gourmand en CPU que NFS, le protocole est plus sophistiqué.
-
SO_RCVBUF=8192 SO_SNDBUF=8192
Double ces valeurs, et reboot smbd.
-
SO_RCVBUF=8192 SO_SNDBUF=8192
Double ces valeurs, et reboot smbd.
Je viens tester : ça redescend à 30 Mo/s.

On doit pouvoir encore gratter en effet, les cores ne saturent pas. Après, ce qu'il faut mettre dans la config, à toi de me le dire ;)
-
Essaye ça:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072
-
Ça reste toujours autour de 50 Mo/s (et les cores ne saturent toujours pas). Par contre en NFS j'explose le compteur aujourd'hui : 90 Mo/s (avec un ralentissement sur la fin, mais c'est déjà très bien).
-
Je viens tester : ça redescend à 30 Mo/s.
Mmhhh, je suis septique avec tes options de no/low delay, ça n'incite pas smbd à remplir ses buffers au max.
-
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.
