bug#24867: 25.1; Gnu Emacs on Windows 8 very slow when VPN connection is used

[herbert kw]

I'm using Gnu emasc 25.1 on Windows 8 and normally I don't have any problems with speed/responsiveness.

I'm launching Emacs with the runemacs.exe

However, when I am travelling and try to connect to my company network via VPN (or just working offline without a connection to the company network), Emacs often becomes incredibly slow - it might take many minutes to open a buffer and it just does not respond to keyboard commands.


I am not connected to the company network, then I have no problems. What could be the problem?

Please excuse my bad English

Greetings Matthias
