Low Performance with Oracle Client 11g R2

Question

Hi Experts
I installed Crystal Report Server 2008 on Windows Server 2003. We use Oracle Client 11R2 to create an ODBC to link with an Oracle Database which installed on another Redhat Linux Server.
I found the performance of generating report by Crystal is really bad, it's a really simple SQL query.
Before the Oracle, we used the SQL Server 2005 as the database, the time to open the same report only took 1-3 seconds, but on Oracle it took more than 20 seconds.
Please help~~ thank you.

Hi Don
Thank you for your reply, I built a report by myself, it's really fast, so I think it's not the problem of ODBC.
I double checked the 'Query SQL' of the old report, it only took 3 tables and generate a SQL like hereafter,
then I checked this SQL on "SQL Developer", it's working fine, very fast.
I don't know why Crystal Report Server take so long time to generate this report.
