清单5对此进行了研究，它打开两个文件——一个文件用于读取，另一个文件用于写入——并让父进程和子进程同时执行读取和写入。
Listing 5 investigates this by opening up two files — one for reading and one for writing — and having both the parent and the child read and write simultaneously.
例如，与其将2GB的数据项写入网格，不如对输入文件迭代读取(譬如每次读取50k)，再将其每次读取的少量数据写入到网格中。
For example, rather than having to write 2gb of data into the grid, we iterate through an input file (say in steps of 50k) and write the read data into the grid.
读取数据流并将结果写入流是很方便的，因为应用程序不一定要将文件的大部分（更不必说整个文件）读取到内存。
Reading data streams and writing results to streams is convenient, because the application does not have to read a large portion of the file, much less the whole file, into memory.
cio允许多个线程并发地对同一个文件读取和写入数据(这个功能应该归功于JFS2的实现方式)，从而允许多个用户同时进行读取和写入操作。
CIO allows multiple threads to read and write data concurrently to the same file, which is due to the way in which JFS2 is implemented, allowing users to read and write simultaneously.
