# [cod] Traffic data question

```Hi,

May I recommend a change to your excel sheet program ?

I would be nice to be able to calculate how many slots you can run on you
connection with a given sv_maxrate.

For instance, I want to run a COD:UO server on a 100Mbit internet backbone
connection.

I know that the absolute maximum bandwidth could be ( 100 * 1024 ) / 8 =
12800 kilobytes / second.

Hence, If I would want to have the sv_maxrate set to 15000 bytes / second I
could in theory setup 873 users on my server. ( 12800 * 1024 ) / 15000 =
873,31...

Well.. ofcourse this is an ideal situation. However, I would like to know
what a normal calculation would look like.

I probably mis something in this calculation, I wonder what .

If someone could point out my mistake in this formula I would be very
grateful..

Regards,

Yuk

Max rate determines who much data is given to each client.  You determine
is. I would not recommend going under 5000, thus you can determine how many

For anyone running IE and you have excel installed check out a quick page I
put together here:

I know I know this is a Linux mailing list but it was the quickest thing I
could through together for my members

I know that max_rate is something to do with limiting the amount of data
that a server sends but can someone tell me exactly what it is to do with.

i.e. is it the amount fo data per client or how much it can send out in
total or am i way off the mark??

Excellent point.. Thanks for that reminder.
This server was just for testing but we have 15000 sv_rate setup..

Thanks,

Paul

don't forget it all depens on the sv_maxrate
