[SOLVED] Long waiting time when connecting to a server

Hy,
when i connect to a server and the map start progress is done, the screen freeze about 5 till 12 second befor i can enter the map. I use showtime = 1 so i can see that the clock is also freezed. It seems the freezing time depends on the server i connect to. My ping is about 50 on all these servers.
Why is this so?

It depends on the server? What happens in single player mode?

I experienced something like this when connecting to a server on the other side of the work (400 ping).

It depends on the server? What happens in single player mode?

In singleplayer mode just right after mapload i'm immediatly in the map.

To make sure that no wrong settings have effect on starting the game, i deleted "C:\users\me\Saved Games\Xonotic" and used a fresh unziped package of v0.7.0 and started up a game. Same happened like i descriped befor. E.g. on "DCC's Plain Delight DM" i ping with about 50ms and i need about 7 Secons after mapload to get into the map:
