FB.Data.query with better performance

Question

I'm using this code for take user's events from facebook:

    var query = FB.Data.query("select eid,name,start_time,location,venue,pic_small,pic_big,description from event WHERE eid IN (SELECT eid FROM event_member WHERE uid={0}) AND start_time >= now() ORDER BY start_time LIMIT 10", 
            uid);                       
    query.wait(function(rows) {
...
}

but it's very slow. is there any way for get better performance?

thanks
