title: Tomcat DataSource - Connection Pooling
body: <p>I am using tomcat datasource connection pool for my app. I have set the max number of connections to 20. I am running 5 concurrent requests at a time. However some  of my calls are timing out because no available connection is found. How long does it take for a connection to get back to the pool once is completed? Are there any properties that would help with this?</p>
  
  <p>I was looking at different attributes in this <a href="http://www.codingpedia.org/ama/tomcat-jdbc-connection-pool-configuration-for-production-and-development/" rel="nofollow">link</a></p>
