What is the fastest type of JDBC driver?
– JDBC driver performance will depend on a number of issues: the quality of the driver code, the size of the driver code, the database server and its load, network topology, the number of times your request is translated to a different API. In general, all things being equal, you can assume that the more your request and response change hands, the slower it will be. This means that Type 1 and Type 3 drivers will be slower than Type 2 drivers (the database calls are make at least three translations versus two), and Type 4 drivers are the fastest (only one translation).
