If you want to only update the IP address of your server and manually open the ports, this unfairly results in connection times being increased. It seems to happen on "SetDomainSocket" where it will take about 1700 ms to get going after "HandleAddress" (~350ms). If you specify Full, it will connect in only the time it takes to handle the address.

Considering that this limits domain operators who are trying to run either multiple domains on the same server or have to manually open ports to play nicely with strict NAT servers (an old rising problem), the connection timing should NOT be this slow, especially if we're telling the client where to go!
