The performance of TWaver Java is obvious to all. What about memory usage? What is the memory growth under different orders of magnitude? What is the impact of view components on memory? We respectively tested to add only the Network Element DataBox to add the Network Element DataBox, and added the Network element to DataBox on the Network display, and added the Network element to DataBox on the Tree display and show the four on the Tree and Network memory usage of different orders of magnitude of network elements, for your reference (the number of nodes on the X axis of the table, in kilobytes; the memory occupied by the Y axis, in MB ): 1. Only add the Network element to DataBox 2. Add the Network element to DataBox and display it on the Network 3. Add the Network element to DataBox and display it on the Tree 4. Add the Network element to DataBox and on the Tree and Network the chart displays the following information: the view component has a great impact on the memory, but the memory usage is less than 500 mb for nodes, which is not bad. During the test, it is found that the system environment has a certain impact on the results. The average value of the test is obtained.
