How much bandwidth usage should I allow for if I had a chat going with X number of people.
Bandwidth is usually very little with chats. One way of calculating usage is:
If one Person sends a message of about 50 characters every 20 seconds or so. This results in the same 50 characters being propagated to everyone else in the chatroom:
From the Web Crossing Server Perspective:
|Total Chars/20 seconds||People In Room||Message from Each User||Received||Sent KB/s|
|1000||50,000||50,000||50,000,000||2441 KB/s (2.4 MB/s)|
So for the high traffic case of 1000 simultaneous users, each sending a 50 character message every 20 seconds, it would take 2.4 Megabytes per second of bandwidth.
