Poor performance when using drop down box on web report

Question

We are using dropdown box functionality in web reporting to allow easy selection of characteristics values. We have 4 dropdown boxes
that represents Region, Area, Country and division.
We need to use booked_values = 'Q' to show only relevant values for selection in the dropdown. However the issue is takes a long time for results to appear
on the template. Read from Fact table is quick but process of deriving drop down values is very slow.
<object>
         <param name="OWNER" value="SAP_BW"/>
         <param name="CMD" value="GET_ITEM"/>
         <param name="NAME" value="DROPDOWNBOX_1"/>
         <param name="ITEM_CLASS" value="CL_RSR_WWW_ITEM_FILTER_DDOWN"/>
         <param name="DATA_PROVIDER" value="DATAPROVIDER_1"/>
         <param name="BORDER_STYLE" value="BORDER"/>
         <param name="GENERATE_CAPTION" value=""/>
         <param name="IOBJNM" value="ZPC_ORG14"/>
         <param name="BOOKED_VALUES" value="Q"/>
         <param name="TARGET_DATA_PROVIDER_1" value="DATAPROVIDER_1"/>
         ITEM:            DROPDOWNBOX_1
</object>
Do you have any suggestions on how to improve performance on drop down?
Thanks, Jay

Dear Jayant Dixit,
1) If the values in the drop down box....are NOT dependent on user selection...then webserver can send them along with the first page....and cache them on client m/c...for multiple client/server dialogs....
2) If the values are changing based on what the user selected from a previous input......then...you need to do some research on how SAP Webserver could optimize the "network traffic"......For example: a) Apache webserver has a module that compresses the content on the webserver side and then send to the client...b)A Client browser plugin decompresses the received packet and displays appropriately....
3) We may need to research the latest SAP webserver capabilities....
Good luck, BB
