Debit 1G sur interface 10G



  • Bonjour à tous,

    Je rencontre un soucis sur un lien entre 2 pfSense.
    Ces firewalls sont connectés via un lien 10G, mais je n'arrive pas à dépasser le 1G lors d'un transfert.

    Voici la config de l'interface parente et des interfaces VLAN (On voit qu'elles sont en 10Gbase-T <full-duplex>):

    ix0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
    	options=e500bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
    	ether b4:96:91:64:c9:60
    	hwaddr b4:96:91:64:c9:60
    	inet6 fe80::b696:91ff:fe64:c960%ix0 prefixlen 64 scopeid 0x2
    	nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
    	media: Ethernet autoselect (10Gbase-T <full-duplex>)
    	status: active
    
    ix0.3100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    	options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>
    	ether b4:96:91:64:c9:60
    	inet6 fe80::b696:91ff:fe64:c960%ix0.3100 prefixlen 64 scopeid 0x8
    	inet 10.255.255.1 netmask 0xfffffffc broadcast 10.255.255.3
    	nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
    	media: Ethernet autoselect (10Gbase-T <full-duplex>)
    	status: active
    	vlan: 3100 vlanpcp: 0 parent interface: ix0
    	groups: vlan
    
    
    ix0.3100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    	options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>
    	ether b4:96:91:26:12:c0

    	status: active
    	vlan: 3100 vlanpcp: 0 parent interface: ix0
    	groups: vlan
    

    Et voici un test iperf entre les 2 pfSense, l'échange ne dépasse jamais les 1000 Mbits/sec:

    Est ce qu'il existe une limitation de debit par session TCP coté PfSense ? Ou quelque chose que j'aurais oublié ?

    Merci d'avance pour votre aide
