Performance Degradation Due To Fragmentation
Memory fragmentation is one of the most severe problems faced by system managers. Over time, it leads to degradation of system performance. Eventually, memory fragmentation may lead to complete loss of free memory.
Memory fragmentation is a kernel programming level problem. During real-time computing of applications, fragmentation levels can reach as high as 99%, and may lead to system crashes or other instabilities. This type of system crash can be difficult to avoid, as it is impossible to anticipate the critical rise in levels of memory fragmentation.
According to research conducted by the International Data Corporation, the performance degradation is largely due to external fragmentation; the lifespan of server is shortened by 33% by external fragmentation alone. This leads to a direct increase of 33% in the yearly budget for hardware upgrades. Thus it can be concluded that memory fragmentation has an undesirable effect not only on memory usage and processing speed of the system but also on hardware components and cost of a project.

Famous quotes containing the words performance, degradation and/or due:
“The value of old age depends upon the person who reaches it. To some men of early performance it is useless. To others, who are late to develop, it just enables them to finish the job.”
—Thomas Hardy (1840–1928)
“In her present ignorance, woman’s religion, instead of making her noble and free, by the wrong application of great principles of right and justice, has made her bondage but more certain and lasting, her degradation more hopeless and complete.”
—Elizabeth Cady Stanton (1815–1902)
“Justice is rather the activity of truth, than a virtue in itself. Truth tells us what is due to others, and justice renders that due. Injustice is acting a lie.”
—Horace Walpole (1717–1797)
