Given the comparable performance to Tomcat's JDBC pool I suspect it is DBCP2. The Tomcat JDBC / DBCP Pool difference are similar to those I have observed with the Tomcat JDBC performance tests (15-20%). Given that the results are in nanoseconds I'm not particularly concerned. As soon as you do any useful work with a database connection a pool overhead of 20,000ns vs. 8,000ns (or 6,000ns vs. 3,000ns) is going to vanish into the noise. I suspect that DBCP takes longer because it is doing more.
