读取与写入文件的三种基本存储方式，一种是普通无缓存存储方式，一种是高速缓存，另一种是异步传输。
文件高速缓存被设置在内存中，从而解决CPU与硬盘访问速度差异太大的问题。高速缓存即在读文件时预读，从而加速访问。异步传输改变内存访问的指令顺序，从而提高了代码执行效率。
本程序通过对三种文件读写操作的时间对比来对比三种方式在效率上的不同。
-Three basic storage read and write files, one is ordinary no-cache storage methods for a cache, another is asynchronous transmission.
The file cache memory is provided in order to address the speed difference between the CPU and disk access much of a problem. When reading a cache file that is read-ahead, thus speeding up access. Asynchronous transfer instruction to change the order of memory accesses, thus improving the efficiency of the code.
This program file read and write operations through three times in three different ways to compare the contrast in efficiency.
