It shouldn't be too hard to run a test with sequential reads that would max the controllers/bandwidth. 1.4 Gb/s is very low, we routinely hit 1gbs doing ndmp dumps from SATA disks on a 3020.

How busy are the CPUs and the disks? Is this more read or write intensive? There are a lot of factors that could be limiting you, to start with I'm pretty sure those controllers top out well before 20gbit is saturated.
Of course if you have a perfstat you can share that'd be an easy way to find out where you are stuck at.

We have installed dual port 10Gbe (x1008a-r6) in our FAS3170A,
configured
them as a vif using lacp, with load balancing as mac.
What we are noticing is that we are only get 1.4Gbits bandwidth per
port.
Even though we should realy be achiving at least 20Gbits.
The filers connect to a 6509 CISCO switch, with each interface
connecting to
a different module for redundancy. The two interfaces from the filer
define
a port channel on the switch so that they reflect the vif on each
filer.
The tool we use to check on the throughput is called Solarwinds and
Orion.
This tool shows that: a. For netapp1, each interface is shown to work at 1.4101Gbits. The
vif is
shown to work at 2.8201Gbits. b. For netapp2, each interface is shown to work at 10Gbits. The vif is
shown
to work at 20Gbits, but we don't get more that 2.8201 Gbits
Is this normal or what are we misising? We have a case open (2001542643) is anyone for NetApp has access.
Thanks
