Report running longer in SSRS than Oracle

I have several long running reports that have been developed in SQL Server 2008 and Oracle.  When I run these reports via SSRS the reports are taking much longer than if I run them in BIDS or SQL Server.  to the point that sometimes the report will timeout and fail on SSRS.  Is there general explanation as to why a report would take so much longer ( sometimes double the time) in SSRS then it is in Oracle or SQL Server without getting into the code for each report.

sometimes the longer runtimes are common, with the report via SSRS rather than run locally. Take a look at the sessiontimeout and sessionaccesstimeout:

Are you seeing significant difference here? When you are running query at the back end, is it performing well?

Most of the time I have seen that the SQL Statement is not correct based on the parameters.

When reports are run in BIDS or SQL Server or Oracle it is a physical execution where it is essentially a client SQL execution i.e. syntax check i.e. spelling & grammar followed by semantics check i.e. presence of tables and columns as well as privileges and then actual execution of optimized query using best plan by optimize takes place.

In SSRS, all this will happen but there will be additional processing as part of reporting service. This is all the more highlighted for low to medium time taking queries. A particular report may be selected to be shown which needs additional time for execution.
