As might be expected, data sharing among SCA components is more expensive across modules than it is for components within the same module, where additional optimizations are available.
不出所料，SCA组件之间的数据共享在跨多个模块时比在同一个模块中使用多个组件时更昂贵，因为后者可以进行额外优化。
Generally, because of just-in-time optimizations, properties are no more expensive than fields.
通常，由于有实时优化，属性的开销并不比字段大。
