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:
“True balance requires assigning realistic performance expectations to each of our roles. True balance requires us to acknowledge that our performance in some areas is more important than in others. True balance demands that we determine what accomplishments give us honest satisfaction as well as what failures cause us intolerable grief.”
—Melinda M. Marshall (20th century)
“The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.”
—Robert Benchley (1889–1945)
“Still be kind,
And eke out our performance with your mind.”
—William Shakespeare (1564–1616)
