Everytime my server reaches more then 2 players from outside the network. My downloadspeed gos down from 1 mbit/s to 4 mbit/s. My normal speed is 18 mbit/s downloadspeed (I can go up to 30 mbit/s). This only happens when runing a tekkit server. This dose not happen when i host vanilla or Tekkit Classic/Tekkit Lite server. What is wrong or what am I doing wrong? Sorry for the bad english :p
