I’ve been working on an internal IT support board and after moving it from the local test server to a remote live server sending the URL out for test, we noticed how damn slow it was, for example, it was taking 10 seconds on every page to connect to a clicked link.

As it was Active Directory secured, changing it to the local AD controller to the server didn’t speed it up as much as I had hoped.

Someone then suggested changing the DB_HOST in the wp-config.php to 127.0.0.1 instead of localhost.

Much to my amazement, the 10 second delay disappeared in an instant. So there you go, a quick fix to the problem and another reminded why I hate using IIS!
