• 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.

    大多数文件系统通过缓冲区缓存来相互通信这种缓存通过缓存最近使用数据优化物理设备的访问。

  • DB2 USES buffer pools to cache the table and index data as they are being read or written to the hard disk drive.

    硬盘驱动器读写索引数据DB 2使用缓冲缓存它们

  • The loss of this data might cause the database to become overloaded, as the cache is no longer acting as a buffer for that subset of the data.

    数据丢失可能造成数据库负荷过多,因为缓存不再充当数据子集缓冲区

  • Using the intermediate buffer on the read side allows the kernel buffer to act as a "readahead cache" when the application hasn't asked for as much data as the kernel buffer holds.

    读取方面使用中间内核缓冲区可以允许内核缓冲区在应用程序不需要内核缓冲区内全部数据充当 “预读高速缓存readahead cache)” 的角色。

  • Note that you can use the sync command to flush the buffer cache out to the storage media (force all unwritten data out to the device drivers and, subsequently, to the storage device).

    注意可以使用sync命令缓冲区缓存中的请求发送存储媒体(迫使所有未写的数据发送到设备驱动程序进而发送到存储设备)。
