Hi, Has you tried to use an framework, tool or caching mechanism for the report? , I heard that the SQL reporting services are useful.

Other causes can be the server has not the enough resources to process all requests. May be you need to scalate resources, even if you are on azure.

You need to find bottlenecks on your script with the sql profiler and sql query analizer.
