A Q came up at Tripwire about bandwidth usage on a full KF server so I tested an application that monitors up and down usage. Here are the results.
An application like DU Meter (//http://www.dumeter.com/) can monitor your bandwidth and report back your up and down usage. It can report in kbps or KB/s as per your specifications. This app has a one month free trial. There may be others out there for free.
Anyway, in this picture running a 6 man server the report came back at:
Receiving: 14.5 KB/s (118.78 kbps)
Sending: 58.2 KB/s (476.77 kbps)
Peak: 60.3 KB/s (493.98 kbps)
At map change there will also be a large spike.
My KillingFloor.ini:
MaxClientRate=15000
MaxInternetClientRate=10000
In this test 5 players were joining from outside the LAN and I was playing via LAN.
If anyone else wants to report there findings with another application it'll help us compare.
