RowIterator loop is slow?

[dan]

Hi,
I was using RowIterator to loop through about 2000 entries in query result
and it took about 3+ seconds. 
I stripped the code to the bare loop structure like below: 
        logger.debug("start loop");
        while (rows.hasNext()){
                Row row = rows.nextRow();
                Value[] values = row.getValues();
        }  
        logger.debug("end loop");

The time for going through the entire RowSet is still 3+ second. Tried with
NodeIterator, the result did not change much. 

Could anyone advise if this is the normal performance? I'm running this code
on a Windows 2003 server.

Thanks,
Dan
