Because of the nature of memory systems and instruction-set designs, the best generic routine to copy memory is rarely as fast as code written to copy a particular length.

There is no direct footprint benefit because each JVM still has a copy of the AOT executable but there are memory and CPU savings from being able to reuse this code rather than repeat the compilation.
因为每个JVM仍然拥有AOT代码的拷贝，所以这种实现方式对于内存使用量没有直接的好处。但是，由于能够重用 AOT 代码并避免重复编译，可以节省内存和CPU。
The result is that system cycles are used to make the copy, as well as maintain two areas of memory largely performing the same function.
结果，系统周期被用于执行复制，并使这两个区域的内存基本上执行相同的功能。
A primary contributor to the complexity of memory management is aliasing: having more than one copy of a pointer or reference to the same block of memory or object.
内存管理复杂性的主要原因是别名使用：同一块内存或对象具有多个指针或引用。
So, not only do we only have one copy of printf on the disk, we only have one in memory.
所以，我们不但可以在磁盘上只有printf的一个副本，而且在内存中也只需要一个副本。
This allowed the system to be distributed over multiple processors, either using shared memory directly as in most Mach messages, or by adding code to copy the message to another processor if needed.
这种设计有利于把系统分布到多个处理器之上，既可以像大多数Mach消息那样直接通过共享内存来传递，也可以在必要的时候增加一点代码把消息复制到别的处理器上。
Theoretically, this file should be a carbon copy of guitars.xml, since no changes were made to the file in memory.
理论上讲，这个文件应该是guitars.xml的完全复制，因为在内存中没有改变该文件。
The display changes when you swap memory pages so you need not copy an Image object from program memory to video memory; you merely change video Pointers and the display changes.
当交换内存页时显示就发生更改，所以您不需要将Image对象从程序内存复制到显示内存；您只要更改视频指针，显示就会发生更改。
The first copy (see Figure 1) is performed by the direct memory access (DMA) engine, which reads file contents from the disk and stores them into a kernel address space buffer.
直接内存存取(direct memory access,DMA)引擎执行了第一次拷贝(参见图1)，它从磁盘中读取文件内容，然后将它们存储到一个内核地址空间缓存区中。
This program tries to store to an unallocated memory location by doing a string copy from arr to the p variable. The expected result is a SEGSEGV signal, as you can see
这个程序试图在一个尚未分配的内存中保存数据：它执行一个字符串复制操作，将arr中的数据复制到p变量中。
The caller fetches the current state of the item from the repository and creates an in-memory working copy based on the state retrieved.

The image is based upon a stopped version of the instance and should not be confused with a snapshot which is a copy of a running instance including its in-memory state.
映像是基于实例停止后的版本，要与快照区分开，后者是正在运行的实例的副本，包括其内存状态在内。
In addition, the middleware can manage these caches to reduce pressure on main memory and copy them between processors to improve workload management.
