AWS i3 与 i2 实例,它们的性能有何不同?

AWS i3 vs i2 instances , what differenctiates their performance?

参考AWS中关于AWS i2实例和i3的区别的post,它本质上是在Intel E5-2686 v4(Broadwell)处理器上使用Amazon Linux AMI,那么究竟是什么使得如果规格相同,i2 和 i3 实例之间的性能差异?

来自Previous Generation Instances

Compared to I2 instances, I3 instances have over 4x higher I/O performance, over 2x higher disk throughput and 18% more SSD per CPU. I3 instances offer Non-Volatile Memory Express (NVMe) based SSDs offering lower disk latencies than I2. I3 offers the lowest price per read IOPS of all EC2 instances.
