Sometimes probably you observ that the network connection is very slow from windows or other OS to linux OS.
This happens because you have a wrong (unsuccessful) configurations.
Some steps to increase to real time the network connections:
1. open a console (or log in to) on Linux server/workstation
2. edit the /etc/hosts file, of course on root mode, or with root rights user
3. add your IP and PC name
4. save the file
