HikariCP

It’s Faster.

There is nothing faster. There is nothing more correct. HikariCP is a “zero-overhead” production-quality connection pool.

Using a stub-JDBC implementation to isolate and measure the overhead of HikariCP, comparative benchmarks were performed on a commodity PC.

Just drop it in and let your code run like its pants are on fire.
