Subject: what is the expeted performance from a dual port 10G card ?

Hello
I have been testing 10G ethernet cards , intel ixgbe, chelsio, tehuti
and melanox . All are dual port cards.
I have used pktgen to test it. A single cpu is mapped over a single
interface (no neeed for MQ , which is quite bad anyway).
Results:
Intel gives: 13Gbps , 6.5 from each port.
The rest give ~10 Gbps .
Cards were tested on PCI-E x8 slot, on a supermicro x7DBI and
supermicro 1025W-UR.

Am i to expect ~20Gbps from each card ?
Thank you.
