Netgear WNDR3800 switch performance

I'm trying the WNDR3800.
Some reviews are reporting less than stellar performance on the gigabit switch.
I've done some testing myself.
Using 2 linux pcs, with gigabit ethernet ports, I've put the first in receiving mode:

# nc -l 1999 >/dev/null

and then I started sending data from the second one:

# cat /dev/zero | nc 192.168.1.2 1999

The result is well over 110 MB/s:

Then, I've repeated the test using a straight cable connection between the two machines:

The result is pretty much the same, so the switch part of the WNDR3800 does not significantly impact performances.
