Processor Scheduling Windows XP Professional uses the Processor Scheduling set-

tings to distribute microprocessor resources among running programs. Selecting Pro-

grams assigns more resources to the foreground program (the active program that is

responding to user input). Windows XP Professional assigns more resources to the

foreground program by allocating short, variable time slices, or quanta, to running pro-

grams. A time slice, or quantum, is a brief period of time during which a particular task

is given control of the microprocessor. When you select Background Services, Win-

dows assigns an equal number of resources to all programs by assigning long fixed

quanta instead. You should select Background Services only when a computer is used

as a server.

options.

Memory Usage Windows XP Professional uses the Memory Usage settings to distrib-

ute memory resources between running programs. Select Programs if your computer is

being used primarily as a workstation. With the Programs option, your programs

will work faster, and your system cache will be the default size for Windows XP
