Without file system caching, Q1 performs similarly on XML and CLOB columns, with a slight disadvantage (10%) for the CLOB column which is not buffered in the buffer pool.

在没有文件系统缓存的情况下，XML和clob列的Q1执行效果类似，不在缓冲池进行缓冲的clob列略微落后(10%)。

This is important in Python programs because file input and output are, by default, buffered; data isn't written as soon as you call a print statement but is instead written in chunks.

在Python程序中这很重要，因为在默认情况下，文件输入和输出是缓冲的；在调用print语句时，数据实际未被写入；相反，数据是成批写入的。

You can also open a buffered binary file by using the form open (fileName, 'b').

您也可以使用open (fileName，' b ')打开一个缓冲了的二进制文件。
