title: H2 datastore EXTREMELY slow? (NOT Really! See EDIT)
body: <p>I just tested the H2 datastore (with Datanucleus 2.x)</p>
  
  <p>The performance is VERY slow. 1/3 of Postgres and 1/10 of MySQL (aprox.)</p>
  
  <p>I was very pleased by the "specs" but i cannot see them in "real usage".

  <p>Is there any performance tuning that i might be missing?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>H2 is not SLOW. Is one of the fastest RDBMS i have tested to date!</p>
  
  <p><strong>I need help explaining WHY i need to CONNECT to the database using the WEB MANAGER (H2 console) to get the fantastic speed of this DB engine...</strong> I accidentally tested my app when CONNECTED through the H2 WEB console "et voilá", problem solved.</p>
  
  <p>Why?</p>
