Savez vous que toutes les cartes réseau ne supportent pas 1 Gb/s ?
La carte PCI suivante (pas toute neuve) limite le trafic à 500 Mb/s !
Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 12)
Connectée sur un PC Intel Core2 Duo CPU E7200 @2.53GHz (largement assez puissant pour iperf) : voici le débit
Avec 3 PC avec des cartes 1Gb/s, j'ai fait des tests croisés : c'est bien la carte réseau qui limite le débit

On va me dire que c'est Linux qui bride la carte.
Voici les résultats sous Windows 7 :

Rien compris. Tu dépasses les 500Mb/s dans l'autre sens ?!
-
As tu un exemple entre plusieurs PC fixes avec des CPU i7 où tu arrives à 1 Gpbs ?
-
Iperf consomme très peu de processeur => cf tests avec un Celeron 600 Mhz (https://lafibre.info/materiel-informatique/test-de-perf-avec-un-celeron-600-mhz/) on fait plus de 300 Mb/s
Je fais le test entre deux PC connecté sur un switch ou reliés directement par le même câble Ethenret.
J'ai a coté de moi un vieux serveur avec un processeur AMD Opteron(tm) Processor 148 @ 2,2 Ghz.
C'est vraiment très lent, comme processeur (simple cœur, non HT)
Il arrive sans problème à faire 1Gb/s mais ses deux cartes intégrés à la carte mère sont en PCI Express :

Pour les 3 PC on est sur de l'Ubuntu.
Je me demande si il est possible de faire 1 Gb/s sur un bus PCI classique...
-
Très intéressant.
Je voudrais moi aussi reproduire ces tests mais je ne possède qu un seul pc équipé 1gbps. En effet mon vieux portable est 100 mbps uniquement.
-
Je vais me faire prêter une carte PCI express la semaine prochaine.
Mon PC Core 2 duo a des connecteurs PCI traditionnels et PCI express donc je vais pouvoir vérifier si c'est le bus PCI qui limite le débit.
Normalement le bus PCI est un bus 32 bits à 33 MHz (soit une bande passante maxi de 133 Mo/s soit un peu plus d'1Gb/s)
-
Tu as peut-être un problème d'arbitrage (PCI Bus Master ?) ou alors un autre périphérique sur le bus PCI utilise un peu de bande passante. Le Southbridge est-il connecté en PCI ? (poste le lspci complet de ta bécane). Sinon ça peut aussi être une limitation d'un bridge PCI-Express <-> PCI.
A l'occasion j'essaierai de faire un iperf depuis un Bi-AthlonMP 2000+ en PCI-X pour vérifier le 1Gb s'atteint facilement avec un vieille gloute (me semble qu'en TCP je ne dépassais pas 500Mb/s et qu'en UDP je montais à 800Mb).

Comment savoir les périphériques qui sont sur le bus PCI 2.2 32bits ceux qui sont sur le bus PCI express ?
Physiquement pour te montrer a quoi ressemble le PC, c'est la machine de gauche sur la photo :
(https://lafibre.info/images/bistro/201212_dell_inspiron_660_15.jpg)
-
surement une limite de la carte réseau ou de la carte mère.
pour voir l'arboresence pci et donc le bus et les autres composants qui partagent la même bande passante:
sudo lspci -tv
pour voir les details:
sudo lspci -v
et encore plus de détails:
sudo lspci -vv
bien mettre les "sudo" ou etre root sinon on voit beaucoup moins de chose.
-
attention aussi en PCI, on est pas full duplex sur le bus PCI mais que half duplex donc fais pas de test en bidirectionnel simultané.
en PCI-e c'est full duplex.

Comment savoir les périphériques qui sont sur le bus PCI 2.2 32bits ceux qui sont sur le bus PCI express ?
Normalement, ce sont les chiffres qui t'indiquent le bus utilisé : le 1er = bus de connexion, le 2ème = l'hote du périphériques suivi du 3ème (séparé par un point) pour les multi-hosts (plusieurs devices sur une même adresse de périphérique). Reste le problème de savoir qui est relié à qui mais là on devine que tu es en full PCI-Express depuis le Northbridge et qu'un bridge PCI-Ex <-> PCI sert à la gestion des PCI dont ta carte réseau. Elle serait donc seule sur le bus PCI car tous les autres sont en '00'.
Sinon la méthode '-tv' est plus efficace ;)
-
L'option tv n'est pas la plus lisible. Je testerais avec un serveur bi-Pentium III pour voir si il vois bien les deux bus PCI ::)

Voici le lspci sur le seul serveur qui ne sois pas bas de gamme auquel j'ai accès.
Il y a 9 bus différents ?
C'est un serveur IBM x3550 1u a base d'un processeur Intel Xeon CPU E5430 @2.66GHz mais la carte mère supporte 2 CPU.

Ton serveur IBM est en PCI-Ex avec :
- 1 bridge PCI pour le chipset VGA et le controleur RAID
- 2x bridge PCI-X pour les deux cartes réseaux
Du coup, chaque carte réseau ayant un bus dédié ça doit "poutrer".

Ce n'est pas la carte car j'ai testé deux carte Ethernet 1 Gb/s en PCI dont une haut de gamme.
J'ai toujours un peu de mal a comprendre le lspci pour savoir si la carte est en :
- PCI
- PCI-X
- PCI Express
Le nombre de bus et quel carte est relié à quel bus.
Pour le serveur IBM, je trouve étonnant que la carte RAID SAS soit en PCI alors que le serveur est en PCI Express. PI le serveur est livré avec deux disque dur de 73 Go SAS 10 000 tr/min en Raid -1

Le truc intéressant avec lspci -v
01:01.0 Ethernet controller: Intel Corporation 82547GI Gigabit Ethernet Controller
Subsystem: Intel Corporation Device 342f
Flags: bus master, [b]66MHz[/b], medium devsel, latency 0, IRQ 18
Memory at fc5e0000 (32-bit, non-prefetchable) [size=128K]
I/O ports at bc00 [size=32]

L'option 66MHz indique que ça ne peut pas etre du PCI normal (meme si la norme le prévoit, je n'ai jamais trouvé de carte mère supportant le 66MHz en 32 bits).

03:02.0 SCSI storage controller: Adaptec ASC-39320A U320 (rev 10)
Subsystem: Adaptec Device 0040
Flags: bus master, 66MHz, slow devsel, latency 64, IRQ 41
I/O ports at 8000 [disabled] [size=256]
Memory at f7ffc000 (64-bit, non-prefetchable) [size=8K]
I/O ports at 7800 [disabled] [size=256]

Capabilities: [a0] MSI: Enable- Count=1/2 Maskable- 64bit+
Capabilities: [94] PCI-X non-bridge device
Kernel driver in use: aic79xx

Option 66MHz et adressage 64 bits -> c'est au minimum du PCI 64 en 66MHz.
La "capabilities" N°94 indique que c'est du PCI-X (fréquence de 133MHz si je ne m'abuse).

Tu risques pas de faire du 1Gbit/s avec du PCI.

Bonsoir
j'ai télécharger le soft pour faire des tests sur ma carte réseau mais rien ne se passe !!
qui peux m'aider svp ?
j'ai windows 7 64bits.

Il te faut 2 PC connectés en Ethernet 1 Gb/s.
PC 1 : iperf -s -i 2
PC 2 : iperf -c 192.168.1.10 -i 2 -r -t 20
192.168.1.10 est l'IP du PC 1, à changer par la vraie IP.

La connexion entre le couple GF 6150LE / Nforce 430 se fait via le bus Hypertransport (plus rapide que le PCI mais même brochage).
-
Je pensais que HyperTransport étais pour la RAM uniquement.
Si la carte graphique intégré à la carte mère est connectée via HyperTransport, la carte Ethernet en PCI, le bus PCI express est vide...
