[cod] CoD4 server requirements: Please rate my hardware

As this is is going to be my first gameserver ever, i have zero experience
with that. My Brother told me, CoD4 Maps are HUGE in RAM, so i was feared
if my 2 GB were enough. Thanks to this list (which is really active
*thumbs up*) i am all pleased and can't wait to install my server.

Now, knowing that my server can handle CoD4:
"see any true traffic analysis of a COD4 server" this could get the next
possible bottleneck. Does anybody already have some stats he would like to
share with us? I'd be really interested in that!

In my Server offer (http://www.hetzner.de/rootserver_en.html /
http://www.hetzner.de/rootserver.html) it says it has a 1Gbit NIC on a
100Mbit Network.
After some eMails with my provider, they told me, i'd have to share
100Mbit/s with 6 other machines. Means, if my rack neighbour runs a
bittorrent DL server, my connection's all f***ed up! ;)

That's the theory so far. I think i'll make some bandwidth performance
tests once i have my server!
