XML comes with a price: It takes longer to encode than binary formats and is much larger to send across a network.
使用 XML 要有代价:与二进制格式相比,编码要花费更长时间,而且经过网络发送时,它更大些。
Binary objects, graphical representations of the page, a re-organized chunk of markup... all of these are harder to send across the network than plain text files.
二进制对象、页面图形表示、重新组织的标记块等等,所有这一切都比纯文本文件通过网络传递要更困难。
