Oracle/thin driver slow

Question

I am running a query on oracle 8.1.7.3 database. when I run it from the command line sqlplus it returns with the result in .5 seconds. when I try the same query from the jdbc thin driver ( 9.0.1 ), it just keeps waiting for 30 seconds.
Is there a known problem with the oracle thin driver ? if so is there a way out of this ?
Thanks,
Dash.

There's no reason why a driver would simply get slower from one version to another. The only explanation I see for this is that you are using scrollable or updatable result sets which is not quite the same as running the query. A scrollable/updatable result set creates a cursor with your query so it's way slower than a forward-only, read-only result set.
As a result, the reason why an older version of a driver might be faster would be that it either did not implement scrollable result sets or it has introduced an option (in the URL or connection properties) to use regular or cursor result sets (e.g. the Microsoft and Data Direct drivers have an option for the type of result sets to be used; if this option is set to cursor, you can use any number of Statements per Connection at the cost of performance).
