3.1. Performance

All Grader functionality should execute instantaneously, except for the following:

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 Grader Tool commands that must access data across a network is subject to potential network delays. The Grader Tool 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 Grader Tool.

There are no specific requirements for the allowable size of a grader in terms of the number of assignments and submitted grades. A Grader on the order of thousands of items is the maximum expected size during normal use.

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

While there may on the order of tens of thousands of registered users, the expected maximum number of users connected to any given server at any given time is on the order of hundreds.

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