Workaround for slow Iis+php+mysql access

IIS7.5 Web site access PHP slow response reason

Online said the god horse disabled IPv6 tried without any effect, and then use the official Microsoft IPv6 Disable tool still so, the following paste the correct solution my method doesn't necessarily apply to you but you might as well try
Because I felt strange when I was using ping localhost on the server, ":: 1"
IIS7.5 Web site access to PHP response slow workaround
Use software such as Notepad or EmEditor to open the Hosts file under C:\Windows\System32\drivers\etc.
Found it:

Modified to:
127.0.0.1 localhost
Save the Hosts file and try the results again?
