          BoneCP is a fast, free, open-source, Java database connection pool (JDBC Pool) library. If you are familiar with C3P0 and DBCP then you already know what this means. For the rest, this is a library that will manage a database connection for you to get faster database access in your application.
          BoneCP is fast! For some tests, it's almost 25 times faster than the next fastest connection pool option, not to mention that BoneCP never spin-locks so it won't slow down your application.
