Thanks, Rick looks like GRO was something we was missing in our setup.
Here are some results form my tests
iperf with GRO disabled on server side : 2,5-3Gbps
iperf with GRO enabled on server side : 3,5-4 Gbps (gro was enabled on
eth0, br-eth0, br-storage)
Additionally i used OVS VLAN splinters option "Enable OVS VLAN splinters
hard trunks workaround" of fuel deployment
iperf with GRO disabled using hw VLAN splinters and MTU 1,5k : ~5 Gbps
iperf with GRO disabled using hw VLAN splinters and MTU 9k : 9-10 Gbps
iperf with GRO enabled using hw VLAN splinters and MTU 1,5k : 9-10 Gbps
Then i tested iperf between machines of 2 different configurations (with
OVS VLAN splinters, and without it),
default->OVS_VLAN_spliters (GRO disabled) : 2,5 Gbps
default->OVS_VLAN_spliters (GRO enabled) : 5 Gbps
OVS_VLAN_spliters->default (GRO disabled) : 2,5-3 Gbps
OVS_VLAN_spliters->default (GRO enabled) : 5-10 Gbps
This looks like OVS is not performing good enough in this setup for
tagged vlans (our br-storage is running on tagged vlan)
any commands?
None that come to mind at present, sorry.
