iscsi multipath with gmultipath

[Niccolò Corvini]

Hi,
I'm testing iscsi multipath with gmultipath, the setup is:
Target: Dell MD3000i with double controller RAID 6
Initiator: Custom server with dual Gigabit Ethernet, FreeBSD 10.3 RELESE

The MD3000 expose the lun on two different subnets, 192.168.253.253,
192.168.252.253. From the initiator i connect to both the ports.

TargetAddress = 192.168.253.253 Connected: da0
TargetAddress = 192.168.252.253 Connected: da1

I have setup the system to use gmultipath:

gmultipath label -v TEST /dev/da0 /dev/da1

And then i've testing the performance, both with active/passive and
actve/active. From what i have seen, the performance don't change that
much, there is some stuff to configure that i'm missing?
Copying form the internal drive to the target
dd if/of bs=1m (4.7GB) A/P 65MB/s
dd if/of bs=1m (4.7GB) A/A 73MB/s

Copying from the target to /dev/null, same file
A/P 101MB/s
A/A 123MB/s


Thanks
