Distributed File System - Performance

Performance

A common performance measurement of a network file system is the amount of time needed to satisfy service requests. In conventional systems, this time consists of a disk-access time and a small amount of CPU-processing time. But in a network file system, a remote access has additional overhead due to the distributed structure. This includes the time to deliver the request to a server, the time to deliver the response to the client, and for each direction, a CPU overhead of running the communication protocol software. The performance of a network file system can be viewed as one dimension of its transparency; to be fully equivalent, it would need to be comparable to that of a local disk.

Famous quotes containing the word performance:

    Still be kind,
    And eke out our performance with your mind.
    William Shakespeare (1564–1616)

    No performance is worth loss of geniality. ‘Tis a cruel price we pay for certain fancy goods called fine arts and philosophy.
    Ralph Waldo Emerson (1803–1882)

    Having an identity at work separate from an identity at home means that the work role can help absorb some of the emotional shock of domestic distress. Even a mediocre performance at the office can help a person repair self-esteem damaged in domestic battles.
    Faye J. Crosby (20th century)
