2 second connection delay when specifying 'localhost' in the client.

[hitchhiker]

Love your project, found something odd, not sure if due to my network setup or something your end.

To test
WatsonTcp, Version=6.0.5.0 / Using your example server / client code (as in vanilla connect).

Problem
If you use create a client and use 'localhost' instead of '127.0.0.1' as the host the client seems to 'pause' for about 2 seconds before being able to connect.

Could be a strange NS lookup thing on my network.
Could be IPV6 interaction.
Could be a bug.

Hi @hitchhiker yes this is likely a pause caused by DNS and resolution to either IPv4 or IPv6. There isn't much we can do about it, unfortunately.
