I'm testing Freenas 8.0.4.

Hardware is a Supermicro board with 2x Intel NICs, Xeon E5620, 32GB RAM.

Network is configured as follows:

Code:
[root@hermes] ~# ifconfig
igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4>
	ether 00:25:90:18:9f:66

	ether 00:25:90:18:9f:66
	media: Ethernet autoselect (1000baseT <full-duplex>)
	status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384

	inet6 ::1 prefixlen 128 
	inet 127.0.0.1 netmask 0xff000000 
	nd6 options=3<PERFORMNUD,ACCEPT_RTADV>
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4>
	ether 00:25:90:18:9f:66
	media: Ethernet autoselect
	status: active
	laggproto lacp
	laggport: igb1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
	laggport: igb0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
vlan56: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=3<RXCSUM,TXCSUM>
	ether 00:25:90:18:9f:66
	inet 192.168.56.10 netmask 0xffffff00 broadcast 192.168.56.255
	media: Ethernet autoselect
	status: active
	vlan: 56 parent interface: lagg0
vlan57: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=3<RXCSUM,TXCSUM>
	ether 00:25:90:18:9f:66
	inet 192.168.57.10 netmask 0xffffff00 broadcast 192.168.57.255
	media: Ethernet autoselect
	status: active 
	vlan: 57 parent interface: lagg0


The NICs are connected to a Dell Powerconnect 5548, ports added to a port-channel in auto (lacp) mode.

This config was working fine at first, was able to push about 900Mbps over the vlan57 interface and stustain it indefinitely. I rebooted for an unrelated reason, and now it's as if the vlan interfaces are at 100Mbps. Running iperf between this box and my other freenas box gets me about 70Mbps (both boxes on same subnet and switch). Running iperf between one of my linux boxes and the other freenas box gets me about 600mbps and that's with about three switches between them.

I'm not dropping any packets that I've noticed, just going slow.

Let me know what other info I can provide.

Thanks,

Matt
