About Cross-Scenario Analysis
Cross-scenario analysis enables you to compare the results of multiple scenario
runs. LoadRunner can superimpose the generated results onto a single cross-
scenario graph. On this graph, you can compare the performance of the server
during multiple scenarios. Cross-scenario analysis is useful for:
·
benchmarking hardware
·
testing software versions
·
determining system capacity
Suppose that you want to benchmark two hardware configurations. You run the
same scenario with both configurations and compare the transaction response
times using a single cross-scenario graph.
Suppose that your vendor claims that a new software version is optimized to run
quicker than a previous version. You can verify this claim by running the same
scenario on both versions of the software, and comparing the scenario results.
You can also use cross-scenario graphs to determine your system's capacity. You
run scenarios using different numbers of Vusers running the same script. By
analyzing the cross-scenario graphs, you can determine the number of users that
cause unacceptable response times.
