Performance issue in SSRS map

Hi All,

For one of my dashboard requirements, I was visualizing revenue information using SSRS MAP (using color codes). I stored all the geography information about the countries in a SQL table. I created a dataset in SSRS, using this table to give input to the map. The map is working fine without any error.

The problem I face is, it is taking around 10 minutes to render this report in reporting server.

Please suggest me some techniques to improve the performance.
