更糟的是，在堆上分配对象时，缓存遗漏还有一个特别讨厌的内存交互。

Worse, a cache miss when allocating an object on the heap has a particularly nasty memory interaction.

新对象是从这个高速缓存的末端分配的，而不必获取堆锁，因此效率非常高。

A new object is allocated from the end of this cache without the need to grab the heap lock, so it is very efficient.

所以，在堆上分配对象，比起在堆栈上分配对象，会带来更多缓存遗漏。

As a result, allocating an object on the heap will likely entail more cache misses than allocating that object on the stack.
