To ensure ZK8's optimal performance, we have done a lot of performance tuning on both server side and client side. To determine the difference in performance between ZK 7 and ZK 8, we have arranged a test, using MVVM and children binding to generate 30 * 30 <div>s and <label>s. Moreover, we used the new feature - Shadow element in ZK 8 to generate the same components. As for the testing tools, we used JMeter to record the average response time, and VisualVM to record the memory consumption of each test case.
