Hi Mike,

What kind of performance ? which Atom ?

For example using using a 1.8 GHz Intel dual core Atom D525 (Jetway NF96FL-525) 
with 3x Intel NIC daughterboard
http://doc.astlinux.org/userdoc:board_jetway_nf96fl-525

[ Mac Pro iperf -s ] <--> [ WAN (Realtek RTL8111 PCI-e) -- (Intel 82541GI PCI) 
LAN] <--> [ MacBook iperf -c (to server) ]

I get a solid 815 Mbits/sec every time.  Both a SIP call and the serial console 
are unaffected by running the iperf test, so a lot of headroom beyond the near 
line speed routing.

If you want to know how many SIP calls can be handled, I don't have a good test 
for that.  Could it saturate 5Mbps up with g711 ulaw/alaw, ~55 calls without 
transcoding, most likely.  Could it saturate 20Mbps up with g711 ulaw/alaw, 
~220 calls without transcoding, probably not.
