# admin-ajax.php – Overload

 * I understand that admin-ajax.php is used to check for new chats.
    However, it
   is being called on all pages even the home page where there are no chats open.
   I tried to turn off chats in the Admin Bar, but it will still run.
 * I am working with sites that get thousands of users a minute and the admin-ajax.
   php is bogging down the server as it is being called every 2 seconds for each
   user.
 * How can I get the polling to only happen on pages where the chat program is being
   displayed.
 * This is a major flaw and should be resolved asap.
 * Thanks

 * Seems like the issue is on
    wordpress-chat/js/mpmudev-chat.js Line: 211
 * You are calling
    wpmudev_chat.chat_session_message_update(); without checking
   any conditions.
 * Either around that call or in the chat_session_message_update: function itself
   there should be a conditional set.
 * For now I just commented out line: 211 and it seems to be working fine now.
 *     ```
       } else {
            //wpmudev_chat.chat_session_message_update();
       }
       ```

 * Hi [@gravitate](https://wordpress.org/support/users/gravitate/),
 * Thanks for posting on the forum.
 * Are you using chat on specific pages using chat shortcode and want the polling
   should only happen on those pages?
 * Please advise.
 * Kind Regards,

 * Yes, that is correct.
    I am only having the Chat on a specific page.
 * It seems to me that there is no reason for the polling to happen on non-chat 
   pages.
 * I suggest running a condition to check to see if the Chat is being displayed 
   before running the Polling.
 * Your init function seems to do that, but there is the }else{ statement that bypasses
   that condition and runs the
    wpmudev_chat.chat_session_message_update(); even
   if there is no chat.
 * Thanks

 * Hi [@gravitate](https://wordpress.org/support/users/gravitate/),
 * Thanks for clarifying that, I see what you mean. I think the plugin may do that
   because of the bottom chat but if you’re not using any chat at all in a specific
   area, it’s definitely helpful not to call that.
 * I’ll run this by the developers, this could especially help in cutting down server
   requirements.
 * Thanks!
