hphpc is in essence a traditional static compiler that converts PHP→AST→C++→x64. We have long been keenly aware of the limitations to static analysis imposed by such a dynamic language as PHP, not to mention the risks inherent in developing software with hphpi and deploying with hphpc. Our experiences with hphpc led us to start experimenting with dynamic translation to native machine code, also known as just-in-time (JIT) compilation. A dynamic translator can observe data types as the program executes, and generate type-specialized machine code.

类型专用的机器代码运行速度更快。除非你是FB那么大，否则不需要这个。使用 APC 或 memcached 以及更传统的方法进行扩展。
