This is less than the 7 seconds maximum in our peak workload plans. The conclusion
is that this transaction is ready for workload testing where we know the round trip
performance will get slower as the transaction competes for resources in a busier
system. Maybe it will stay below the 7 seconds maximum when the peak workload
number of purchase steps are executed together, maybe not.
Carrying the thought one step further, it has been found to be very benefi -
cial from a test management perspective to plan for the round trip performance
testing of all transactions or representative transactions of all groups individually
in an empty system. After recording the results on the peak workload plans, you
should alert the developers as to which transactions did not perform under the
maximum response time allowed by the software requirements. There is no need
to start workload testing of these transactions yet because they already exceed
their performance boundaries. In contrast, the transactions that did perform under
the maximum response time allowed by the software requirements are ready for
workload testing. Draft 4 shows what the extended workload plans might look like
with the round trip performance results in an empty system. Round trip perfor-
mance numbers with a (green) notation indicate that the transaction group on that
row is ready for peak workload testing. Round trip performance numbers with a
(red) notation indicate that the transaction group on that row is not ready for peak
workload testing.
