My site is running slow, because the file "admin-ajax.php" is loaded many times. see screenshot here: http://f.cl.ly/items/2b0O3Q0X27433X2F2j3U/Bildschirmfoto%202013-02-23%20um%2014.13.14.png
Here the functions.php file: http://f.cl.ly/items/3e2D070u2M310W1J321K/Bildschirmfoto%202013-02-23%20um%2014.19.46.png
How can i disable the file on the frontend and why is it loaded so many times?! Can i reduce it to only ONE time?
Thanks!
admin-ajax.php
. You will break all kinds of things. Looks to me like you have a very poorly written theme or plugin. I can't tell which. You need to find out what is causing those requests. They aren't normal. Switch to a default theme and disable you plugins one by one and try to isolate the problem.
