It's also important that you understand how the virtual function table works, so you understand the extra steps that can decrease performance that take place when you call a virtual function (each object has a virtual function table pointer hidden from you in its structure data , and to call a virtual function, you need to follow that pointer to the table, and then jump to the function pointer contained within, which can hurt caching).

理解虚函数表是如何工作的也同样重要，这样你就能够理解当你调用虚函数时需要的额外步骤，这些步骤会降低性能(每个对象都有一个隐藏的虚函数表指针，这样调用一个虚函数，你需要根据这个指针找到那个函数表，然后跳到它所包含的函数指针所指的函数里，这会降低cache的效果)。

"Often we can't move on because we haven't yet learned what we're supposed to from a difficult situation," Kase says. After contemplating whether I'd actually gained some insight from my suffering, I realized I now have a clearer sense of what I need and don't need from my inner circle.
