+If your application opens and closes connections a lot (for example, for each request), 
+you should consider using a  <a href="tutorial.html#connection_pool">connection pool</a>.
+Opening a connection using <code>DriverManager.getConnection</code> is specially slow

 <h3>Use a Modern JVM</h3>

 Newer JVMs are faster. Upgrading to the latest version of your JVM can provide a "free" boost to performance.
