于是最优化归结为两类：建立一个有效的蓝图(调优你的配置)、有效使用运行时设施(使你的应用设计最优化)。
Optimizations then fall into two major categories: establishing an effective blueprint (tuning your configuration), and making effective use of runtime facilities (optimizing your application design).
可预测的是，上面的调优版本免除了所有处理程序成本，并使性能提高了一倍。
Predictably, in the above tuned version, the entire cost of the handler has been removed and performance doubled.
目前，这个调优实用程序的适用范围还不够大，IBM 希望在将来的版本中进一步增强该实用程序，以便更精确地描述 ODBC 数据源的能力，并使更多的操作可以下推到 ODBC 数据源。
While its current scope is very modest, IBM hopes to enhance the tuning utility in future releases to more accurately characterize the capabilities of and improve pushdown to ODBC sources.
