    Hi,

    Google has started Considering the Load Time as an Important Factor while Ranking a Website at Index time.

    Common reasons for a site to get load slowly.

    The Time For Loading A Web Site Depends Mostly On:

    1. The number / size of external resources included in the site.(Images , Feeds)

    2. If Images are not properly optimized and resized. (Large and Heavy Images)

    3. The database queries executed while the site loads. (Many database queries at the same time)

    4. Use More Flashy Effects and High Resolutions Images. (If Flash has been used with heavy images)

    I Hope This Information Helpful For You All.

    Thanks.

    5. Too many PHP files that need to be included, parsed, compiled and executed.
    6. A lot of AJAX requests.
    7. Overloaded webserver (Too many stuff needs to be swapped).
    8. Not using PHP Bytecode caches.
    9. Network overloaded or too many users share the same server.
    10. Hosting offshore leads to too many network hops.
    11. Not using loadbalancing for big sites.
    12. Not using content dilivery networks which are optimized for speed. Amazon's storage services for example.
    13. Too many stuff parsed/done with PHP.
    14. Not using ETags in your Webserver.
    15. Wrong cache configuration (Expire tags)
    16. No splitting up of dynamic and static content.

    There are plenty more by the way :)
