You can write trace data to a file continuously as an extension to the in-storage trace, but instead of one buffer per thread, at least two buffers per thread are allocated.
可以连续地将跟踪数据写到文件中，作为存储内跟踪的扩展；但是在这种情况下不是为每个线程分配一个缓冲区，而是至少分配两个。
These two events are often specified together because between them they cover the most common ways of loading the contents of an existing file into a buffer.

Most of the file systems communicate through a buffer cache, which is a cache that optimizes access to the physical devices by caching recently touched data.
大多数文件系统都通过缓冲区缓存来相互通信，这种缓存通过缓存最近使用的数据来优化对物理设备的访问。
Users can stream the output data into a string, an internal buffer, the standard output, or a file.
用户可以使这些输出数据流入字符串、内部缓冲区、标准输出或文件。

而且，对于那些受益于文件系统预读功能或者较高缓冲区缓存命中率的应用程序，可能会出现性能的降低。
You can point it at another file quite easily; it's a bit harder to, for instance, read from a buffer.

Log records are written first to the log buffer in memory, and then to the log file, most commonly when the log buffer is full or a commit occurs.
日志记录首先被写到内存中的日志缓冲池，然后再写到日志文件，通常是在日志缓冲池已满或者发生了一次提交时写到日志文件的。
The journal is a special file that logs the changes destined for the file system in a circular buffer. At periodic intervals, the journal is committed to the file system.
所谓日志就是一种特殊的文件，它会在一个循环的缓冲区内记录文件系统的修改，然后将其定期提交到文件系统。

在清单2中，图像已经在图像缓冲区中，我们只需将它保存到磁盘上的文件中。
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。
Journaling file systems use a journal to buffer changes to the file system (which is also used in crash recovery) but can use different strategies for when and what is journaled.
日志文件系统是使用日志来缓冲文件系统的修改(同时也可以应用于紧急故障恢复)的，但可以根据记录的时间与内容采取不同的策略。
Buffer cache can be updated by setting the shared_buffers parameter in the postgresql.conf file.
可以通过设置postgresql . conf文件中的shared _ buffers参数来更新缓冲区缓存。
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。
The code reader creates a character buffer from the source file, the scanner combines characters into ITokens, and the parser combines ITokens into IASTNodes.
代码阅读器从源文件中创建一个字符缓冲，扫描器将字符组合到IToken中，解析器将IToken组合成IASTNode。
The readfile function dumps the entire contents of a file or Web page to the default output buffer.
readfile 函数将把文件或Web页面的全部内容转储到默认的输出缓冲区。
Before extracting audit records from the db2audit.log file, flush any remaining audit records in the buffer out to disk by issuing the following command.
在从db2audit. log文件提取审计记录之前，发出以下命令将缓冲区中的所有审计记录刷新到磁盘。
The first copy is performed by the DMA engine, which reads file contents from the disk and stores them into a kernel address space buffer.
DMA模块从磁盘中读取文件内容，并将其存储在内核空间的缓冲区内，完成了第1次复制。
Worse, while it can grow, it cannot shrink, so LeakyChecksum permanently retains a buffer as large as the largest file processed.
更坏的是，它可以增长，却不可以缩小，所以LeakyChecksum将永久保持一个与所处理的最大文件一样大小的缓冲区。
The transferTo() method causes the file contents to be copied into a read buffer by the DMA engine.
transferTo()方法引发DMA引擎将文件内容拷贝到一个读取缓冲区。
