How to See The Response In LoadUI NG Pro & How to Judge Performance from LoadUI NG Pro

LoadUI NG simulates a lot of requests at once, so it is not built to show responses from the server. Use the targeted SoapUI NG  test case to do this - LoadUI NG just runs it a lot of times at once. If you want to make sure your server returns the response you need, use SoapUI NG assertions.

As for performance, you can monitor server metrics in the Monitoring tab and request metrics in the Statistics tab. Not sure how you plan to judge performance, so cannot give more concrete advice.

Hope this helps. :)
