Before the values in these locations can be used, however, it is
important to understand the way that response time is calculated. The
intention of counting response time is to understand the amount of
time it takes to reach one of the three measured events (input
operation, output operation, or quantum expiration) . The user may,
for example, type a command. The response time is the lag between the
time the monitor accepts the command and the time it takes to reach
one of the three events. Note that this does not include the time the
user spends typing the command. The response time is counted in
jiffies (ticks).
The Responses Subtable collects response times for the first event for
a job when it begins running a program. If the first event for a
program is to output a * as a command prompt, the amount of time
between the time the "RUN program" command is accepted by the monitor
and the time the monitor sends the * to the user's terminal is
measured as the response time for that program. If a job runs a
program that immediately begins input from the terminal, the response
time for that action is the amount of time between the time the "RUN
program" command is accepted by the monitor and the time the terminal
input operation is attempted. The response times are accumulated for
all the jobs as they are scheduled to run.
