Maybe it would help to read the documentation of the software you use:
Here comes part of the javadoc of DriverManagerDataSource:

/**
  * Simple implementation of the standard JDBC DataSource interface, configuring
  * a plain old JDBC Driver via bean properties, and returning a new Connection
  * for every <code>getConnection</code> call.
  *
  * <p><b>NOTE: This class is not an actual connection pool; it does not actually
  * pool Connections.</b> It just serves as simple replacement for a full-blown
  * connection pool, implementing the same standard interface, but creating new
  * Connections on every call.
  *
  * <p>Useful for test or standalone environments outside of a J2EE container,
..
