Advanced table copy and delete slow when done programatically

Question

I am modifying a line in an advanced table, then copying it and deleting it. What I noticed is that
it takes a lot less time to copy and delete manually within the application verses doing it programatically.
To copy or delete 10 lines it takes about 1 or 2 seconds within the form. When I do this programatically
it can take up to 20 seconds. Does anyone know why it takes so much longer?
Here is a sample of my code.
          porequisitionlinesvorowimpl.setSelected("Y"); //programatically select line for copy
     ArrayList deletearraylist = null;
     String s1 = porequisitionlinesvorowimpl.getItemNumber();
          java.sql.Connection connection = oadbtransaction.getJdbcConnection();
          //Query values from for child item.
          OraclePreparedStatement oraclepreparedstatement = null;
          ResultSet resultset = null;
          try {oraclepreparedstatement = (OraclePreparedStatement)connection.prepareStatement("SELECT I2.DESCRIPTION WHERE                       I.SEGMENT1 = ?");
                           int i = 1;
                           oraclepreparedstatement.defineColumnType(i++, 12, 240);                                                                 oraclepreparedstatement.setString(1, s1);
                           resultset = oraclepreparedstatement.executeQuery();
                           while(resultset.next())
                                //Collect values from query for child item.
                                String desc = resultset.getString(1);
                          porequisitionlinesvorowimpl.setItemDescription(desc);
                          //Copy modified parent to produce a child line.
                          ArrayList copyarraylist = new ArrayList(2);
                           copyarraylist.add("populateAndDuplicate");
                           copyarraylist.add("lines");
                           executeServerCommand(oapagecontext, oaapplicationmodule, "CheckoutLinesSvrCmd", copyarraylist);
                           } //while loop for resultset
          resultset.close();
     oraclepreparedstatement.close();
          catch(SQLException sqlexception) {
               ErrorUtil.handleFatalException(oadbtransaction, sqlexception, this);
          //Delete original Kit Parent           
          deletearraylist = new ArrayList(2);
          deletearraylist.add("populateAndDeleteReqLines");
          deletearraylist.add("lines");
          executeServerCommand(oapagecontext, oaapplicationmodule, "CheckoutLinesSvrCmd", deletearraylist);

I timed these too and they appeared to completed very quickly. The only events that took a significant amount of time where the calls to the executeServerCommand when I copied and deleted lines.
Can the database connection and looping the resultset be slowing these activities down?
There is no VO existing that generates the query results I am looking for. Do I need to create my own VO?
