How can I eliminate slow resolving/loading of localhost/virtualhost (a 2-3 second lag) on Mac OS X Lion?

Question

Since setting up my development environments on Mac OS X Lion (brand new macbook air purchased in January 2012), I have noticed that resolving to a virtual host is very slow

Answer 1

Specifying same host for IPv6 ::1 helped me.

127.0.0.1 something.local.mydomain.org
::1 something.local.mydomain.org
