Description: 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.
