Query operation being performed in backend when Loading layers

Hi,

 

We recently create a iOS application with ArcGIS integration. The application uses a MapServer URL and
1. Loads the base map

2. Loads different layers defined by the user

 

But when the map is loaded or even when the map is zoomed there is large amount of data usage, 4-8MB per zoom action. When checked log on the mapserver there are a lot of query hits, please find the log snippet below

=======

FINE    Nov 20, 2015, 11:24:24 AM    REST request successfully processed. Response size is 983215 characters.    Secure.MapServer    appuser

FINE    Nov 20, 2015, 11:24:24 AM    End Query    Secure.MapServer    appuser

FINE    Nov 20, 2015, 11:24:23 AM    Begin Query    Secure.MapServer    appuser

FINE    Nov 20, 2015, 11:24:23 AM    REST request received. Request size is 377 characters.    MapServer    appuser

=======

 

Can you please tell me, if the loading the layers or zooming the map is so costly. Is there any alternative
