speed with BE2012

Hi all,

i have just install the new 2012 BE vray and playing now arround with it.

I hope i can use it instead of veeam. Dedup seems to be as good as veeam dedup. Only the performance is not the same. 

By backing up vmware client to the dedup storage is this my rate: 1700 MB/min (BE 2012 is a hardware server)

My Veeam system is backing up with this rate: 4500 MB/min (the system is ofocurse an vm guest)

My old BE 2010 reach this rates: 4500 MB/min (hardware server as well, but store the jobs on the FC Tape)

The new server has two 1GB lan cards, is there a possibility to use them both to encrease the performance?

Thanks all
