The most important factors in determining swap space size are the requirements of the system's software applications. For example, large applications such as computer-aided-design simulators, database-management products, transaction monitors, and geologic analysis systems can consume as much as 200-1000 Mbytes of swap space.

Consult your application vendor for swap space requirements for any application whose data files typically exceed 10-20 Mbytes in size.

If you are unable to determine swap space requirements from the application vendor, use the following guidelines to allocate swap space:
