Both overall file system overhead and efficiency issues relating to individual file storage can play a role here.
要兼顾总体文件系统开销和与各个文件相关的存储效率问题。
In general, cooked files are slower because of the additional overhead and buffering provided by the file system.
通常，熟文件更慢，因为存在附加的开销和文件系统提供的缓冲。
Without file system caching, this overhead is mitigated by the fact that XML columns are buffered in the DB2 buffer pool and CLOB columns are not.
在没有文件系统缓存的情况下，xml列在db2缓冲池进行缓冲而clob列则不是，从而可降低开销。
This obviously has the result of reducing its footprint on our file system, as well as the overall bandwidth overhead when we are moving the file around.
这样做都可以明显地减少文件在文件系统中占用的空间大小以及移动文件时所需的全部带宽负载。
Sendfile (2) is a technique that avoids buffer copy overhead, and it directly pushes bits from the file system onto the network.
Sendfile(2)是一种避免缓冲区复制开销的技术，并且它直接将数据位从文件系统转移到网络。
