It is a false comparison. It is comparing jdbc-pool to DBCP 1.x. tomcat-dbcp is based on DBCP 2.x. > Have we considered > promoting it to the default connection pool implementation?

The performance numbers are broadly similar. tomcat-jdbc had a slight edge last time I checked but the differences are in the noise compared to even the most basis database operation. The reason for that edge is that tomcat-jdbc doesn't do everything by default that tomcat-dbcp does.

Once thing tomcat-jdbc does a lot better than tomcat-dbcp is JMX. That is the primary reason I haven't followed up on this thread: http://tomcat.markmail.org/thread/o4d2qalqf7267gl6 Mark --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
