**Compare Different Node Configurations**  

It’s always interesting to compare the performance between different configurations, such as comparing startup latency of different machine types, different numbers of pods, or comparing resource usage of hosting different number of pods. The dashboard provides a convenient way to do this. Just click the "Compare it" button the right up corner of test selection menu (region (e) in Figure 1). The selected tests will be added to a comparison list in the "COMPARISON" page, as shown in Figure 3. Data across a series of builds are aggregated to a single value to facilitate comparison and are displayed in bar charts.

Title: Comparing Node Configurations in the Dashboard
Summary
The dashboard allows users to compare the performance of different node configurations (e.g., machine types, pod numbers). By clicking the 'Compare it' button, selected tests are added to a comparison list on the 'COMPARISON' page. Data from various builds are aggregated into single values and displayed in bar charts to facilitate the comparison.
