When I connect from Windows XP to a Unix Samba share, I can do it fast, if I take only user and password. If I take "Server IP\user" and password, it takes 15 seconds more to connect. The server IP is calculated using "gethostbyname" every time before trying to connect this way. The time amount for this calculation is not included in the 15 seconds. Where can the time difference come from?
