I have this CR connect to Oracle database, it runs okay inside CR2008, but its extremely slow when i run it from .NET by using ExportToStream (PDF) function.

How should i improve the performance? Thanks a lot for any hints/help!

By calling ExportToStream, your code is actually doing a couple of things.

1.  Running the report and rendering it.  This is the only step that happens when you run the report in Crystal.
2.  Converting the report to PDF
3.  Converting the PDF to a binary stream and sending it to wherever it goes.

If it is a large report that has many pages, then steps 2 and 3 are going to take a while.

A computer only does what you actually told it to do - not what you thought you told it to do.
