my Intel teamed NICs are slower than a single NIC
Posted on 2008-06-13
I have the following
1.) switch
3Com Switch 4200G 3CR17662-91
Software Version: 3.01.00s56
2.) two NICS
Intel Pro PM 1gb nic
Intel Pro PL 1gb nic
most recent drivers and Intel ProSet with ANS installed
Switch Config
-have setup aggregated ports on switch
NIC Config
-have tried team setup as SLA (Static) for aggregate bandwidth
-have tried team setup as DLA (Dynamic) for aggregate bandwidth
PROBLEMS
1.) as SLA I run the test utility on Intel ProSet DeviceManager plugin and it explains that switch is not configured properly
2.) as DLA it seems to be teamed fine, Windows shows it as 2gb NIC, but my performance is slower then when on a single NIC
can anyone help, I can get all the other detail you need

What about the speed and duplex settings, what about the patch cords (UTP Cables) are they fine. Do check these settings.

I have not ventured from defaults on the switch or NICs on speed and duplex settings, patch cords are all of the highest quality, I have much Intel and 3com doc on both SLA and DLA teaming, just cannot find what I am missing
with the LACP 802.3ad nic teaming 3com told me that when in a peer to peer session, one host to another, they are still talking to each other at gigabit, you see the benefit when there are two or more to peer connections, unless there are multiple hosts all teamed and talking to other hosts that are teamed you will not see the aggregated bandwidth
