I have a report which returns large result set. When I execute the report from VS.NET 2008 or directly report SQL query in SQL Management Studio it takes about 30 seconds.

But when I execute the report in a standard way via web browser (IE, Chrome) using report URL it takes 85 seconds.

I am new to SSRS. Is this a normal overhead? I can see high values in TimeProcessing and TimeDataRetrieval columns in Execution log (each 40000), TimeRendering is just 115.

When I use caching I have a response within 1 second so I do not think this is a communication issue when returning result set back to web browser. Unfortunately I cannot use caching in my case.

Please, could anybody explain to me where a problem is or if it is possible to tune it somehow?

Many thanks.

IS your Reporting service all on the same server?

I tested it in configuration having all SSRS components on the same server and also in configuration where ReportServer database is on dedicated SQL server. Report accesses always database which is on different SQL server.

I have similar results in both cases.
