We had a problem before, where the PHP page does not load as fast as it should on mySQL database access. We seem to have solved it by allowing the 127.0.0.1 to point to localhost.
What we did was removed the comment sign # to resolve the ip as localhost.
Host file is found at the following directory: c:\windows\system32\drivers\etc\
File name is hosts.
There are a lot of source material on the internet to edit the host file.
This is one of them:
