I have create a web site (PHP, MySQL) for the intranet of my campus. The campus network has a proxy and web servers but I've used a PC in my workgroup as the server using XAMPP 1.7.7 for testing purpose. When I visiting the web site from the different PC in the same workgroup it takes more than 30 seconds to load the index page or other pages.
The web browser used is Firefox and it has bypass the proxy server for the local addresses. The index.php page is only 5KB of the size. And in the index.php I have destroyed current session if there any, database connection to retrieve latest 03 news and call two external css files. Used less than 5 images (total capacity less than 5 KB) in every page. The XAMPP is in default settings.
Is there something that I can do to optimize and decrease the loading time. Your opinions are welcome.
