after testing severals loadbalancing (LACP) types with Cisco, we saw,
that we never get more than 112MB/s with two network cards and iperf.
So, we tested without loadbalancing, 4 Clients (iperf -f M -c <ip>) and
two target IPs. Every IP has his own 1Gb/s network card.
On the end, two clients had a connection to IP 1 and the second two to
First we used the two onboard NICs and then, one onboard and one
external NIC, but without success. We never get more then 112MB/s
All are connected through a Cisco Catalyst WS-X4515.
The mainboard is a Intel S3420GP.
