title: Fastest OLEDB read from ORACLE
body: <p>What would be the fastest way of retrieving data from the Oracle DB via OLEDB?</p>
  
  <p>It should be portable (have to work on Postgres and MS SQL), only one column is transfered (ID from some large table).</p>
  
  <p>Current performance is 100k rows/sec.  Am I expecting too much if I want it to go faster?</p>
  
  <p>Clarification:</p>
  
  <p>datatable has 23M records</p>
  
  <p>Query is: SELECT ID FROM OBJECTS</p>
  
  <p>Bottleneck is transfer from oracle to the client software, which is c++/OLEDB</p>
