Game freezes for a second when somebody connects or disconnects from the server.

[Flum91]

Like the title is saying, i'm suffering from freezes and these happen 9/10 times when somebody connects or disconnect from the server. They also seem to be more appearent when a server has a high number of players.

 

Is anybody having or had the same issue and found a fix for it. These freezes or driving my crazy as the always happen in dogfights or when moving on the ground.
