First Browser Login takes ages


i’m using on my Laptop Linux and Firefox.

I have only trouble if i wanna login per Browser. The first Login is taking a long time. After that i can switch the libraries without any “lags”.

Same problem is when i switch to the system admin. First time is taking a long time as well.

Just would like to know, why?

I haven’t any problems with the clients. It’s just the Browser - Login.
