Silk Performer 17.0 introduces a number of new features and enhancements for Performance Explorer. In this blog post, we're going to show you the 4 most important ones: (1) The new User Type Comparison Report: Including the Region Comparison Report and the Custom Comparison Report (formerly named Cross-Load Test Report) you have now three types of comparison reports available for extensive analysis. (2) The new Comparing Graphs feature: With just two clicks, you can now compare a specific measure with the same measure from all other user types, agents, or regions. (3) The new Export to Excel feature: Simply export your Performance Explorer charts or tables to a Microsoft Excel spreadsheet. (4) The new Tree Filter: It allows you to quickly access measures in the tree, which is especially useful when you have to deal with many nodes and deep hierarchies.
The user type comparison report
First, we're going to explore the new user type comparison report. A comparison report shows load test results side-by-side, which allows you to comfortably compare them. You might already know the region comparison report. The user type comparison report is just the same. However, it does not display the results of your cloud regions but the data of your user types. This is especially useful when you have many user types. Assumed, you have to load test a responsive website. This usually means that you have to create many user types to cover a number of end user devices, resolutions, browsers, connection types, bandwidths, and so on.
To create a user type comparison report, first click a node in the tree. You can select, for example, the Client Measures, the Overall, or the User Types node. Depending on your selection, the content of your comparison report will vary. Then click the Reports tab and User Type Comparison Report. Note that it does not make sense to select a cloud region node for a user type comparison report. In such a case, the button will be disabled. Let's assume you have selected the User Types node beforehand. The report then shows one column per user type. You can then, for example, drag the Overall node onto the report, to add an Overall column to the comparison. Remember that you can always drag additional nodes from the tree onto your reports and charts in Performance Explorer.
Note that the report that was formerly named cross-load test report, now appears as Custom Comparison Report in the Reports tab. Take a look at the following user type comparison report. It contains four columns, three user type columns and one overall column, which is the baseline.
The compare graph feature of Performance Explorer now provides new options. You can now compare a measure with the same measure from all other user types, agents, or regions. Create a chart and add a measure. Make sure to select the measure in the measure list, then click the Results tab and Compare Graph. Take a look at the following screenshot. We first created a new chart and dragged the measure Server busy time from the Overall node onto it. Then we clicked Compare Graph With Other User Types. Performance Explorer added this measure from the other three user types to the chart.
Exporting charts as Excel documents
You can now export your Performance Explorer charts as Microsoft Excel documents. All you have to do is to create your chart in Performance Explorer and customize it to your liking. Then click the Chart tab and Export as Excel document. Performance Explorer opens Microsoft Excel, exports the necessary data and automatically creates a chart.
The tree filter
The new tree filter in Performance Explorer allows you to quickly access measures by entering a string into the field above the tree. This is especially useful when you have to deal with complex trees with many nodes and deep hierarchies. When you drag nodes from a filtered tree onto a chart or report, only the filtered measures will be added. To reset the filter, click the red x.
The new user type comparison report, the advanced comparing graphs feature, the export to Excel capabilities, and the new tree filter: these are the most important new features in Performance Explorer 17.0.
