AtomicInteger与Integer的性能差异 [英] Performance Difference of AtomicInteger vs Integer

问题描述

AtomicInteger和Integer之间是否存在性能差异?

Is there any performance difference between AtomicInteger and Integer?

推荐答案

这两种类型的选择不应取决于性能. AtomicInteger的主要选择是如果您希望通过对整数进行操作来实现线程安全.

The choice of these two types should not depend on the performance. The main choice for AtomicInteger is if you want to achieve thread safety with the operations on the integer.

但是，性能差异可能很大程度上取决于所选的操作系统，因为原子操作的详细实现取决于操作系统.

However the performace difference might strongly depend on the choosen operating system, as the detailed implementation of atomic operations depend on the operating system.
