Hi All,
My home PC has max perfomance approx. 800 Mbit/sec (measured between
two re adapters and a cheap d-link switch in between them).
I've just test ffec performance (one of re's is the other side):
-----
% ifconfig ffec0
ffec0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80008<VLAN_MTU,LINKSTATE>

media: Ethernet autoselect (1000baseT <full-duplex>)

Here is the vmstat at the time of iperf test:

Is this an expected result? Assuming that the system was about 65% idle,
there is a space for improvement.
The system:
