Full list of user on first page with rtmedia

When I active the rtmedia plugin.
The full list of user are listed on the first page if the user is not login ( I have 1800 users ),
/* <![CDATA[ */
var BP_Suggestions = {"friends"
....
}
/* ]]> */

and only the friends of the user, if the user is login.

They are not shown on the webpage, but the webpage it makes the webpage very heavy to load.

I have buddypress activated.
