Load Balancing
A system can consist of independent components, each able to service requests. If all the requests are serviced by one of these systems (or a small number) while others remain idle then time is wasted waiting for used system to be available. Arranging so all systems are used equally is referred to as load balancing and can improve over-all performance.
Load balancing is often used to achieve further gains from a distributed system by intelligently selecting which machine to run an operation on based on how busy all potential candidates are, and how well suited each machine is to the type of operation that needs to be performed.

Famous quotes containing the words load and/or balancing:
“The only human beings I have thoroughly admired and respected in the world have been those who carried the load of the world with a smile, and who, in the face of anxieties that would have knocked me clean out, never showed a tremor. Such men and women end by owning us, soul and body, and our allegiance can never be shaken. We are only too glad to be owned. Religion is nothing but this.”
—Henry Brooks Adams (1838–1918)
“Men are to be guided only by their self-interests. Good government is a good balancing of these; and, except a keen eye and appetite for self-interest, requires no virtue in any quarter. To both parties it is emphatically a machine: to the discontented, a “taxing- machine;” to the contented, a “machine for securing property.” Its duties and its faults are not those of a father, but of an active parish-constable.”
—Thomas Carlyle (1795–1881)
