ExecuteQuery(ForwardOnly):
Use ForwardOnly Cursor Mode if you will traverse through the record set from FirstRecord using NextRecord and will not return to a previous record.
ExecuteQuery():
If ForwardOnly cursor mode is not mentioned, it will be defaulted to ForwardBackward and to support this Siebel system has to create a Cache to maintain the entire record which would degrade the performance.
