Since version 15.0 of Silk Performer, you can merge the results of several load tests and view these results in a single report in Performance Explorer. This is especially useful when you split up a big load test to start it from multiple controllers. When the split up load tests are complete, Silk Performer will generate multiple result folders (one folder per controller) and multiple reports. To view all metrics in one aggregated comprehensive report in Performance Explorer, you need to merge the individual results. Merging load test results in Silk Performer is quite simple: Start Performance Explorer, click Wizard in the main menu and click Merge Load Test Results Wizard . Now drag two or more result folders onto the table. Note that you cannot merge results from different projects. First off, select a Master load test. Some result values, like the description, cannot be merged. In such a case, Silk Performer will use the value of the master load test. Next, select absolute or relativ as your Merge type . If you're wondering what absolute and relative mean in this context, here's a quick explanation: absolute : In a report, the results will display with their actual start time on the time line. For example: If you started a load test on Controller B 10 seconds after you started the load test on Controller A, the results will display on the time line accordingly. relative : In a report, all results will display with the same start time on the time line, regardless of the actual start times of the load tests. Now you can select an Interval for the merged time-series data files. The minimum value from the Interval list is the lowest common multiple of the intervals from all time series data files that are located in the specified results folders. And finally, specify a folder where the merged results are to be stored - a Target folder - and click Merge . When the results are merged successfully, Performance Explorer displays an overview report. This newly created report has the workload type Merged Workload, which contains all executed usergroups. You see: merging results of two or more load tests in Performance Explorer works like a charm and is available since Silk Performer 15.0.
