Projects / PoolMan


The PoolMan library and virtual JDBC2.0 driver provide Java object pooling, with particular extensions for database resources and caching SQL queries/results across multiple databases. PoolMan eliminates a common bottleneck in enterprise apps and maximizes JDBC performance for servlets, Java Server Pages, and other Java database applications.

            PoolMan cut my build time by 4
            In about an hour, I had poolman set up inside my build. A full build with a lot of jdbc tests used to take about eight minutes. Now it takes two minutes, and the tallest poll in the tent is javadoc instead of database access.

            Good product. Easy to configure.
