parse.com - Slow Parse requests with php -

i have issue parse requests.

i'm using website show stats of ios app. make requests parse using php stats of app in real time. page loading of website slow though. have wait 1 real minute load single page. i'm hosting website on private heroku server. plus, parse dashboard not slow website. heard parse have requests limits... ? true ?

i make requests this:

$query = new parsequery("categories") $query->descending("createdat"); echo($query->count()); // use query data instead of 

sometimes, use many requests on same table. example :

$query = new parsequery("relations"); $query2 = new parsequery("relations"); $query3 = new parsequery("relations"); 

i because have select different columns queries. didn't find way save query in variable. wish this:

$query = new parsequery("relations"); $query2 = $query; $query3 = $query; 

i increase website performances it's impossible...

any idea?
