Comparing the response times of each command ID

370
Chapter 12 - Reporting Performance Testing Results
Percentile
Compares the response times based on the percentile that you
select. The percentile must be in the Performance report. For example, if the
Performance reports calculate the 50, 70, 80, 90, and 95 percentiles, the
Compare Performance report must use one of these percentiles.
s
The style of the comparison relative to the base Performance report:
Value relative to base report
Compares the response times relative to the base
Performance report. With this option, the first column in the report (the base
Performance report) is always 1, and the other columns are relative to it. For
example, if the base report lists a response time as 2.5 and another report lists
the response time as 5, the Compare Performance report lists them as 1 and 2.
Absolute data values
The indicated response times appear in the report. For
example, if the base report lists a response time as 2.5 and another report lists
the response time as 5, the Compare Performance report lists them as 2.5 and 5.
s
The weight of the response times that occur most frequently:
Individual sample data
The response times are not weighted. A command ID
that occurs ten times and a command ID that occurs 100 times have an equal
influence on the response time statistics.
Weighted by count of base report samples
The response times are weighted to
reflect the frequency of occurrence of the command ID to which they
correspond. Command IDs that occur more frequently have more influence on
the response time statistics, and command IDs that occur less frequently have
less influence on the statistics.
Note:
For more information about advanced options, see the TestManager Help.
What's in Compare Performance Reports?
A Compare Performance report can compare reports in a number of ways. It can
compare reports absolutely or it can compare reports relative to a base report. In
addition, the response times can be weighted so that command IDs that occur
frequently have more influence, or they can be unweighted so that each command ID
has equal influence.
There are four versions of the Compare Performance report:
