You can load multiple experiments or experiment groups simultaneously in Performance Analyzer. By default, when multiple experiments on the same executable are loaded, the data is aggregated and presented as if it were one experiment. You can also look at the data separately so you can compare the data in the experiments.
To compare two experiments in Performance Analyzer, click the Compare Experiments icon in the toolbar and select two experiments to compare.
Most data views support comparing experiments. In comparison mode, the data from the experiments or groups is shown in adjacent columns. The columns are shown in the order of the loading of the experiments or groups, with an additional header line giving the experiment or group name.
Use the style buttons in the Compare Status panel. For the Comparison Style, you can specify one of the following:
Shows the metrics values for all loaded experiments.
Shows the +/- difference between metrics for the baseline experiment and the other loaded experiments.
Shows the difference between metrics for the baseline experiment and the other loaded experiments as a ratio. For example, a comparison experiment metric might display as x0.994 to indicate its value relative to the base experiment.
For tips and more information about the Compare Status panel, see the Performance Analyzer help.
