Slow throughput on teamed NIC's
I have Backup Exec Small Business 2012 installed on my new media Server SBS2011.
The server has 4x 1 GB NIC on one Teaming Load Balanced.
When I backup a client (Win7 x64 with SSD) it seamed the media-server works on half duplex.
The load is 50 % on NIC2 on reading and about 50 % on NIC 3 with writing to NAS.
But when I copy a big file with windows explorer form \\client\C$ to \\NAS it runs with 99% on reading and writing.
Is it a configuration problem?
Thanks for any help.
