So, from these few examples, you can see that network latency is
introduced in places 2,3,5,10 hops away from you that neither you nor
your provider have any control over, nor hopes of fixing.
Now, what I came here to say: YOU CAN'T ASK THE QUESTION "HOW MANY
PLAYERS CAN I SUPPORT" AND EXPECT A REALISTIC ANSWER, assuming that you
are talking about player experience, or people playing on a LAN.
BTW, I work for Internet Systems Consortium ( www.isc.org
<http://www.isc.org/> ) on the BIND
and DHCP training and support team. We get questions all the time
asking "how big a server do I need to serve X number of zones and to
support Y number of recursive clients... I CAN'T ANSWER THAT QUESTION
EITHER, and for mostly the same reasons.
Thanks for your time and patience in reading this entire e-mail.
{and if you've actually read this far, please quit asking about sizing
servers, K? THX!}

people ask this question for me not to put my nose directly <br>
into it... here goes.<br>
<br>
As with my day job, these questions can't really be answered without<br>
knowing a lot more about the environment. Yes, lots of things =
depend on<br>
CPU, disk, ram, etc. but your network connection is much more important. =
<br>
<br>
I have yet to see any true traffic analysis of a COD4 server, so I =
can't<br>
tell you how many instances you could run over a true 100mbit LAN<br>
connection.<br>
<br>
When people say "I have a 100mbit connection", that's all well =
and
good, <br>
as that is what you have decided to pay for.<br>
<br>
I doubt, however, that your provider gives you that full 100mbit to =
the<br>
outside world.<br>
<br>
Take as an example, my house. I have a gigabit switch between =
some<br>
servers, 100mbit in most rooms, and 54mbit wireless. With all of =
the<br>
wonderful infrastructure, I still only have 4Mbit to the outside =
world<br>
(thanks, Timewarner for not offering FIOS). I guess that I could =
claim<br>
that my COD4 server has "GIGABIT CONNECTIVITY", as it is =
connected to<br>
the gig-e switch.... that does not mean that traffic coming out of =
my<br>
server to the outside world is anywhere near gig speeds.<br>
<br>
Even if your provider has multi-gig connections to the outside world, =
<br>
consider how many other people they have sold "100mbit" =
connections
to?<br>
<br>
It doesn't take many people cranking full 100mbit flows to flood a =
gig<br>
network... See if you can get your provider to give you their <br>
oversubscribe numbers. How many 100mbit connections are they =
selling on<br>
that 10gig interconnect? Does it look possible?<br>
<br>
Then, you have to consider transit latency. Even if your provider =
has<br>
multi-gig connections to their provider, think about where the flows =
<br>
pass over exchange points. When I look at the output of =
traceroute, I<br>
see a couple of places that it is obvious that network traffic is<br>
hitting some sort of roadblock.<br>
