After all the design, code generation or recompiling, and performance tuning, the next critical step to deploying a complex application is that a benchmark phase occur.
在完成所有的设计、代码生成或者重新编译、性能优化之后，部署复杂应用程序的一个关键步骤是进行基准测试。
However, there also exists a means to determine the location of the table and have code execution occur close to the data in the case where performance is critical.
不过在性能关键的地方，也有办法获知数据表的位置，并且让代码在尽量靠近事发数据的位置执行。
This 20% of code is on the "critical path" and it is these areas that are worth optimizing for performance.
