I have 9 servers running with 128 tick. One of them is DM FFA with 16 players, and the rest is competitive and retakes.

I want to know how I can calculate each server bandwidth usage.

I have an average of 70~80 simultaneous players, but when all servers get full (~90 players), all the servers start to get loss. And I'm sure that the problem is the bandwidth.

The value it's unstable, it goes around 1% and 12%, sometimes it goes to 0%.

I have 100mbps download and 50mbps upload (12,5 mb/s and 6,25 mb/s , respectively).

I've alredy downloaded iftop and vnstat, but I can't understand the output of them.

NOTE: I DON'T want generic numbers ("a server with 10 players and 128 tick uses XXX of bandwidth"). I want to know how to calculate this for my server.
