All scheduling, viewing, and options commands must execute instantaneously, except for the following:

• the time to generate a schedule must be on the order of seconds
• the time for Instructors to log in to their own account must be instantaneous,except for any delays due to network transmission of data from the central host to the local computer
• the time to view a generated schedule must be instantaneous,except for any delays due to network transmission of data from the central host to the local computer

The time to execute all administrative commands must be instantaneous, except for any delays due to network transmission of data from the central host.

In general, the performance of Scheduler commands that must access data across a network is subject to potential network delays. The Scheduler must transmit data as fast as is possible on any given network, but delays due to external network circumstances are beyond the control of the Scheduler Tool.

There are no specific requirements for the allowable size of a generated schedule in terms of the number of scheduled classes. A Schedule on the order of tens of items is the maximum expected size during normal use.

The maximum expected sizes of the Scheduler Tool databases are the following:

• Instructors Database -- up to hundreds of records
• Courses Database -- up to hundreds of records
• Rooms Database -- up to hundreds of records

The Scheduler Tool must be able to operate with calendars and databases of sizes larger than these normal maximums. However, the tool need not the meet the previously-enumerated time performance requirements for calendars or databases larger than normal maximum sizes.
