User perception tool

An article comprising one or more machine-readable storage media containing instructions that, when executed, enable a processor on a server of a computer network system to:

• time a first part of an event on receiving a user action on a thin client;
• time a second part of the event on sending a request for a process of the user action from the thin client to the server via a network;
• time a third part of the event on processing the user action at the server;
• time a fourth part of the event on providing the processed user action to the thin client via the network;
• time a fifth part of the event on displaying a result of the processed user action on the thin client;
• generate a data structure of data;
• and
• compare the time of the first, second, third, fourth, and fifth parts of the event with the data structure of data to create results of the computer network system performance;
• wherein the instructions, when executed, enable the processor to determine a maximum time such that a user of the thin client perceives the performance to be tolerable and to generate a first setpoint based on the maximum time and enable the processor to compare the time of the event with the first setpoint and to produce an indication of undesirable performance in response to the time of the event being greater than the first setpoint.
