最后，团队采取了多项优化措施，包括针对应用程序的特定部分，从对象数组切换到索引数组，从类切换到结构体等。

In the end, the team ended up switching from object arrays to index arrays and from classes to structs, amongst several other optimizations, for that particular part of the application.

对于局部数据，使用结构体而不是类。类被存储在堆；而结构体被存储在栈。

Use structs instead of classes for local data. Classes are stored on the heap; structs on the stack.
