Round trip performance for peak logon workload
Next we test each transaction group with its Saturday workload volume. Figure 9.4
shows the fi rst results of testing those transactions individually at peak workload
before we mix them into one workload. First we test and confi rm that the log on/log
off response times are well below the requirement maximum for the Saturday peak
workload for that transaction.
Next, in Figure 9.5 we test and confi rm that the purchase steps response times
are well below the requirement maximum for the Saturday peak workload for that
transaction.
