Socket Server Bandwith...?

I just got done building a local socket server for multi user in Flash…(GO ME!!!)… however, I am unaware of bandwith usage… does any have an idea on how to find out the bandwith usage???

I am sure I am doing this the wrong way… but I am sending data to the socket server on an onEnterFrame (so every xx fps)… is this bad? I am sure I am not too sure so that is why I am asking here. Thanks!
